How Does Angular Work?

As discussed, Angular is a framework for building web applications using HTML and JavaScript. Also, it uses a TypeScript language that makes it easy for the developers to compile it to JavaScript.

After having a look at what is Angular, the main question arises: how does Angular work? To answer this question, you need to understand the basic concept of working on Angular applications.

The framework typically follows Angular architecture patterns that consists of several Angular component libraries, some the core and some optional.

Angular architecture patterns

From the above diagram, we can see that the framework follows Angular architecture patterns and is usually divided into 8 main blocks:

  1. Modules

    For every Angular application, you will have only one root module named AppModule. The root module usually provides the Angular developers with the bootstrap mechanism that makes it easy to launch the new application. Modules are the one of the most essential aspect, if you’re understanding what is Angular.

    An app typically contains many functional modules. Let’s say you are planning to use another custom Angular module for your application; then, it becomes mandatory for you to register the same module in the app.module.ts file.

    One of the best option is to hire Angular developers from reputed organization where they can easily organize the source code into distinct functional modules. It helps you in managing the complex web application development and designing for reusability.

  2. Components

    Like modules, every Angular project contains at least one component, the root component. The primary role of the root component is to connect the component hierarchy with a page document object model (DOM).

    Inside every component, the developers define the class that contains application data and logic. Moreover, the Angular material components are associated with the same HTML template that defines the view displayed in a target app. The Angular components control a patch of the screen called a view.

  3. Templates

    Angular templates are nothing but a combination of HTML and Angular markup. The primary aim of such an Angular template is to modify HTML elements before they are displayed quickly. In addition, template directives provide program logic, and binding markup connects your application data and the document object model (DOM).

    Generally, there are two types of data binding.

    • Event Binding: With the help of Event Binding, you can efficiently build an app that efficiently responds to user input in the target environment by updating your app data.
    • Property Binding:Angular is a component-based framework that supports Property binding where the developers interpolate values computed from app to fetch data into the HTML elements of the web page.
  4. Metadata

    Metadata is nothing but an instructor that informs Angular about how to process a class. It is designed explicitly to decorate the class so that the developers can quickly configure the expected behavior of a class.

    If you are working with the Angular 2+ version, decorators are one of the essential concepts you need to deal with. The user can use metadata to a class to tell the Angular app that AppComponent is the main root component. In addition, metadata can be attached to the TypeScript using the decorator.

  5. Data Binding

    The Angular data binding concept typically handles real-time communication between a template and its related component. Moreover, data binding is also a boon for communication between parent and child components.

    Angular allows communication between a component and the DOM, making it very easy to define interactive applications without worrying about pulling and pushing the data.

  6. Directives

    Angular components and directives are interconnected with each other. In simple words, we can say that directives and components both are essential building blocks of Angular applications.

    One such Angular directive is ngClass, a better example of the existing Angular attribute directive.

  7. Services

    The Angular developers create a service class when no specific data or logic is associated with the particular view. In addition, the developers can even share the data or logic among different components.

    The @Injectable decorator immediately precedes the service class definition. The decorator provides the metadata that allows your service to be injected into client components as a dependency.

    The main functionality of the Angular framework is to distinguish components from services. And it leads to increase modularity and reusability for your application. For example, once the developers separate a component’s view-related functionality from other processing, you can make your component classes lean and efficient.

  8. Dependency Injection

    The primary role of the Angular developer is to keep the component classes short and straightforward. And that’s what Dependency Injection (DI) does.

    DI is not responsible for fetching data from a server, validating the user input, or logging directly into the console. In addition, they are accountable for delegating such tasks to the services.

    DI is equipped with the AngularJS framework and is typically used by developers everywhere to create new components using the user input validation system with the services. Components consume services; you can inject a service into a component, giving the component access to that service class.

Advantages of Angular Framework

Let’s highlight some of the biggest and most beneficial advantages of Angular that bring convenience to building web applications for your business needs.  Moreover, the biggest advantage that we can say for sure is that there are many leading websites built using the Angular framework.

Advantages of Angular

  1. Supported by Google

    One of the biggest advantages that have come up with the Angular framework is the Long-Term Support (LTS). Google offers long-term support for Angular, which help you to deal with Google’s plan to keep using the framework and expand the Angular ecosystem.

    The exciting part about Angular ecosystem is that Google employs Angular and plays a vital role in improving the performance of the web application. With its active support of LTS, Angular help you scale your web application easily.

  2. TypeScript

    TypeScript is the primary language that is built explicitly for Angular application development. TypeScript is nothing but a superscript for JavaScript, and it allows for optimal code quality, making the web application more secure.

    Its active support of TypeScript helps Angular developers easily detect and eliminate mistakes early to deal with completely rewrite the code or performing maintenance operations.

    Browsers will not execute TypeScript directly. First, the Typescript code must be “transpiled” into JavaScript with the help of tsc compiler, which requires some updates in Angular configuration file.

  3. Declarative UI

    With the help of dynamic HTML elements, the user interface (UI) of the Angular application is built. HTML is a more simple language as compared to JavaScript programming language. Angular is also a declarative and easy-to-use language that exclusively supports directives such as ng-app, ng-model, etc.

  4. POJO (Plain Old Java Object)

    POJO approach is included in the Angular framework. The developers do not need to use Angular’s getters and setters method.

    By including POJO, the developers find it easy to perform object manipulation via all of JavaScript’s standard functionalities. Moreover, one of the best Angular practices that developers can perform is to simply quickly remove or add properties from the things while also iterating over them as needed.

  5. SPA and PWA

    One of the most cost-effective methods for website development to make it behave like mobile apps is a Progressive Web App (PWA). It is responsible for minimizing the network requirements and, most importantly, enhancing the web app performance.

    Single-page web applications (SPA) may be written primarily when the developers need to utilize the server-side rendering capabilities of Angular. Moreover, single-page web applications it helps the developers to load the home page quickly and improves website performance on mobile and low-powered devices.

    You can even make use of Angular Ivy to compile components more independently of each other quickly for your business applications.

  6. Simplified MVC Pattern

    The Angular framework typically uses the MVVM (Model-View-ViewModel) architecture rather than an MVC (Model-View-Controller). With the help of the MVVM model, the developers can efficiently deal with two-way data binding between View and ViewModel.

    In addition, Angular platform allows the developers to deal with the automatic propagation to change within ViewModel’s state to the view. ViewModel data strictly uses the observer model to inform changes to the ViewModel model to model.

  7. Modular Structure

    The entire Angular source code is grouped into different essential web page elements like Angular components, directives, pipes, and services. Modules are considered to be the heart of the Angular framework’s intuitive application structure. The developers can easily deal with framing the features of applications using the entire tree structure smoothly.

    Modules play a vital role in lazy loading. In simple words, by including modules in the Angular application, you’ll find featuring differential loading functionality of the application website’s on-demand turns to be faster.

    With the help of Angular, you may develop a complex app while dividing work and ensuring organized and generated code. When you have a solid grasp of these, you may make the most of the modules. Modularization might enhance developer efficiency in certain situations.

    So, these are the best advantages of using Angular framework that you need to be aware of while developing a robust web app for your business needs.

Drive your business growth with intuitive applications.

Limitations of Angular Framework

It’s time to highlight some of the drawbacks of the Angular framework. But with the recent updates, the Angular community is working hard to remove such limitations.

Advantages of Angular

  1. Limited Search Engine Optimization Options

    Generally, the Angular framework comes up with the platform’s limited Search Engine Optimization (SEO) options and poor accessibility for search engine crawlers. And it’s one of the major drawbacks of using the Angular framework.

    Being that Google is the number one search engine on the planet, we can’t imagine this problem will continue to persist for much longer before a solution is presented in another update.

  2. Steep Learning Curve

    Another glaring con of using the Angular framework is that it can be quite difficult to learn.

    With such a complex web of modules, coding languages, integrations and customizing capabilities, understanding Angular definitely takes some time.

    Fortunately, Angular provides phenomenal support and there are a number of online tutorials and courses you can take to catch up and start taking full advantage of all the program has to offer.

  3. Migration

    One of the reasons that companies do not use Angular frequently is the difficulty in porting legacy js/jquery-based code to angular-style architecture. If I talk about jQuery vs Angular, both are meant for different perspectives. Also, each new release can be troublesome to upgrade, and several of them are not backward-compatible.

  4. Performance

    Dynamic applications didn’t always perform that well. Complex SPAs could be laggy and inconvenient to use due to their size. One of the primary reasons that why we use Angular is the enhancing the performance of your business web applications.

  5. Lacking CLI Documentation

    Some developers express concerns with the current state of CLI documentation. While the command line is very useful for Angular developers, you won’t find enough information in their official documentation on GitHub and you have to spend more time exploring threads on GitHub to get answers.

What are the Angular Best Practices That You Need to Follow?

Understanding and following Angular best practices is one of the most essential factors for both developers and business owners. Let’s highlight some of the common Angular best practices that you need to consider while developing web application.

  • Make a habit of using Angular CLI.
  • Utilize the ES6 functionality to make robust web app
  • Creating and maintaining proper folder structure
  • Use Lazy loading feature as and when required
  • Always following the coding practices for Angular development
  • Use “trackBy” along with ‘ngFor’
  • Use Interfaces to deal with object literals

By taking care of the above Angular best practices, let’s move to the section about how to develop Angular applications from scratch.

What are Angular Development Tools?

The Angular development process is made easier by utilizing the best tools, especially for developers. Herein, we’ve highlighted the list of the best Angular development tools that will make work easier for developers to perform coding efficiently.

  • Karma: Makes your code testing process smooth. You can quickly recover from potential flaws, errors, and defects using the Angular testing framework.
  • Jasmine: No need to rely on any browser or other JavaScript testing environment. With its easy-to-use syntax, Jasmine allows you to write and test the code easily.
  • Protractor: You can quickly perform testing Angular applications directly on the software, and such tests can be easily synchronized to the page.
  • Webstorm: It is considered to the best IDE for performing coding efficiently. The Angular developers find it relatively easy to deal with best coding practices.
  • Mocha.js: It’s a robust testing framework that typically deals with asynchronous testing functionalities.
  • Angular Kickstart: Its easy-to-use interface allows you to work with faster satisfaction of all your business needs.
  • Angular Fire: It is solely responsible for fostering dynamic API features, three-way data binding, and other essential features.
  • Djangular: You’ll get a reusable application with responsive app integration with the AngularJS framework.
  • Rest-angular: This Angular development tool is solely responsible for dealing with large data consumption from REST API.
  • Ng-inspector:This tool enables browsers with an inspector panel, helping developers to develop, debug, and understand develop Angular applications quickly.

How To Create Angular Application?

I hope you’re now clear with what is Angular. Right? So let’s move ahead and focus on essentials steps to create an Angular application from scratch. We will discuss the complete step-by-step guide on how to proceed ahead with a new Angular application.

Before that, the developers need to analyze the list of the best Angular development tools to make the web app development process smooth.

Step 1: Angular CLI Installation

Angular CLI (Command-line Interface) is the official and main tool for creating Angular applications. To install CLI, we need to provide the following command: npm install -g @angular/cli.

Step 2: Angular Project Initialization

To initialize the Angular application, first of all, you need to navigate to the location where you want to keep your project.

cd ~
ng new angular-application”

So, it’s the first and most important step that is going to be used for creating a new Angular application. Once you give this command, the CLI will prompt you with multiple options that you want to configure for your application.

creating angular application

Step 3: Adding Angular HttpClient

Now, we need to import HttpClientModule to our app.module.ts file.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
import { EmployeeComponent } from './employee/employee.component';
import { AdminComponent } from './admin/admin.component';

declarations: [
imports: [
providers: [],
bootstrap: [AppComponent]
export class AppModule { }

Likewise, whatever the components you add, do not forget to import them; otherwise, it will throw an error. When the developers are dealing with asynchronous operations like an HTTP request, you need to deal with promise in Angular development.

Step 4: Creating UI Components

As stated earlier, Components are the building blocks of Angular application. Creating an Angular component is simple.

creating ui components

Here, we have created the “employee” component. And as you can see that all the essential files are automatically created by the Angular CLI makes you create a rich user interface..

created by the angular cli

Likewise, let us create one more component (admin) in our Angular application. So, now we have two components employee and admin.

Step 5: Adding Routing Functionality

We will perform the redirection of the empty path to the employee component. This, in order, will constitute the first-time users’ automatic redirection to the home page.

You’ll need a class, technically known as resolver in Angular, development that is solely responsible for implementing the Resolve interface of Angular Router.

We’ll be running the following set of routes into our src/app/app-routing.module.ts file:

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { EmployeeComponent } from './employee/employee.component';
import { AdminComponent } from './admin/admin.component';
const routes: Routes = [
{ path: '', redirectTo: 'employee', pathMatch: 'full'},
{ path: 'employee', component: EmployeeComponent },
{ path: 'admin', component: AdminComponent },
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
export class AppRoutingModule { }

This way, we can work with the Angular framework. Yes, it is the basic concepts that help you create a simple Angular application from scratch.

Summary of Angular Framework

After having a detailed look at what is Angular framework, we can give a final summary:

  • For front-end development process, Angular is a one-stop solution for developers. Apart from Angular, ReactJS is also best option for it. If we talk about Angular vs React, they are equally important for web app development. It involves the applications client-side and has little to do with the back end.
  • Angular is best utilized for completing advanced, large-scale Angular projects under the direction of a seasoned developer.
  • The developers can easily add Angular elements to projects utilizing a different platform, such as React or Polymer.
  • Google supports the Angular framework.
  • This program is not up to par with SEO best practices, so opt for a different platform if your primary focus is search engine optimization.
  • Angular is a JavaScript framework—not a JS Library.

I hope you got a clear understanding of the Angular framework and its usage. If you are planning to build a new web application for your business needs, Albiorix is a one-stop solution for Angular development services.

TypeScript VS JavaScript : Key Differences You Must Know

TypeScript and JavaScript are the two leading technologies that play a vital role in web application development. As a result, JavaScript has been the most popular programming language among the developer’s large community.

But, with the invention of TypeScript, the picture has changed completely. Do you know how? TypeScript is considered the enhanced version of JavaScript with some additional features.

In this blog, we will explore the differences between TypeScript vs JavaScript in detail. We will start by explaining the basics of each language and their respective features. Then, we will compare the two languages based on their performance, scalability, maintainability, and other factors. Finally, we will discuss some use cases for each language and provide tips on choosing the right language for your project.

Key Takeaways

  • TypeScript is a superset of JavaScript that adds static typing and other features to make it more scalable and maintainable.
  • JavaScript is a programming language used primarily for creating interactive web pages and web applications.
  • The main difference between TypeScript and JavaScript is that TypeScript is a superset of JavaScript that adds static typing and other features, while JavaScript is a dynamic and interpreted scripting language without built-in static typing.

Understanding the Concept of Static and Dynamic Languages

Static and dynamic are terms used to describe web application programming languages based on how they handle data types and variable declarations during compilation or runtime. A static language is one in which the data types of variables are determined at compile-time and cannot be changed during runtime.

In other words, the variable type is declared when the code is written, and the compiler checks to ensure that the variable is used correctly. If there is a mismatch between the type of a variable and the operation performed on it, the code will not compile. Examples of static languages include Java, C++, and TypeScript.

On the other hand, a dynamic language is one in which the data types of variables are determined at runtime, and variables can change their types during execution. In other words, variables are not declared with a specific type and can be used in any way.

The interpreter or runtime environment checks the type of a variable only when it is used. If there is a type mismatch between the variable and the operation, the program throws a runtime error. Examples of dynamic languages include JavaScript, Python, and Ruby.

The choice between static and dynamic languages depends on the project’s needs. For example, static languages can catch more errors at compile-time, making it easier to write and maintain larger and more complex codebases.

They can also provide better performance since the compiler can optimize the code based on the specific data types used. However, they may require more code to be written due to the need to declare variable types explicitly.

On the other hand, dynamic languages can be faster to develop since they require fewer explicit type declarations and can be easier to read and understand. As a result, they are often used for scripting and web development, where rapid prototyping and flexibility are essential. However, they may be more prone to runtime errors due to the lack of type checking at compile time.

What is JavaScript?

JavaScript is a client-side and server-side language. The primary reason that JavaScript is a scripting and interpreted language is that it’s not compiled before execution. Instead, the primary usage of JavaScript is to create dynamic web pages.

Javascript offers HTML and CSS as two major languages that provide structure and style to web pages. On the other hand, JavaScript is a popular scripting language that will provide you to create interactive web pages with responsive elements that improve user engagement.

And if we talk about the history of JavaScript, it was originally developed by Brendan Eich of Netscape Communications Corporation, initially called Mocha, then LiveScript, and finally a new language in the newer versions renamed to JavaScript.

What Is JavaScript Used For?

Javascript is one of the best scripting languages used explicitly by developers globally for creating dynamic and interactive web content-like applications.  Almost 97% of all websites primarily use JavaScript as a popular scripting language. So, if you have basic scripting knowledge, you can quickly build responsive web apps for your business needs.

JavaScript offers you to develop different applications like software, hardware controls, and servers. In addition, due to its native behavior to the web browser, JavaScript is considered a well-known web-based language.

JavaScript is used for:

  • Easily adding impressive behavior to create interactive web pages.
  • Creating web and mobile apps.
  • Building web servers and developing server applications.
  • Speeding up the performance of the application.
  • Developing front-end development as well as back-end development.
  • Performing the data structure and reference validation on the web browser itself.

What is TypeScript?

Developed by Microsoft, TypeScript is an open-source programming language that quickly compiles to JavaScript. TypeScript is not just a scripting language but also a set of tools that help you make web development easier.

what is typescript

From the above diagram, we can easily see that TypeScript is JavaScript with added features designed explicitly to overcome JavaScript data grid libraries setbacks. TypeScript is beneficial to many developers to have basic scripting knowledge regarding static type definitions, Javascript libraries, and handling code complexity. And it plays a major role in understanding the difference between TypeScript vs. JavaScript.

And it plays a major role in understanding the difference between TypeScript vs. JavaScript.

What is TypeScript Used For?

TypeScript is a superset of typed JavaScript that allows developers to build and manage large-scale JavaScript projects. In simple words, we can say that Typescript supports JS libraries with additional features like strong & optional static typing, code compilation, and object-oriented programming.

TypeScript is used for:

  • Simplifying JavaScript code, making your application easier to read and debug.
  • Quickly building web applications using highly productive web development tools for JavaScript IDEs and practices, like static checking.
  • Quickly coding for all complex and large applications.
  • Availing all the benefits of ES6 (ECMAScript 6), static typing plus more productivity.
  • You can developed mobile and web applications with TypeScript web development company.

What are the Different Types of TypeScript?

TypeScript is a powerful and intuitive language that specifically contains various basic types, such as Number, Array, Tuple, Boolean, String, and many more.

It’s a fact that some of these essential types are not available in JavaScript. If you want to know more about such types of TypeScript, you can visit the official TypeScript documentation.

Furthermore, below are some other types that are expressivity of TypeScript:

  1. Any & Unknown

    Any (anything that you wish) is best used for covering unknown is its type-safe system. The primary usage of any is to allow the developers to easily assign JavaScript variables to the code. It’s widely used to describe incoming variables that are not yet being validated and whose type definitions is unknown.

    And if we talk about Unknown, it’s exactly similar to Any, but it will not allow you to do anything with it unless it’s explicitly type-checked in your TypeScript development.

  2. Void

    Void is specifically used by developers when there is no value returned. Generally, it’s used for the return type of function that returns nothing.

  3. Never

    If something is never going to happen, we can use Never as the return type. One such good example is an exception-throwing function directly into the TypeScript code.

  4. Intersection & Union Types

    This option allows the developers to easily create custom types as per the code logic. Intersection types let you combine several basic types into one type.

    Let’s say, we have custom type Employee which contact empl_fname:string and empl_fname:string. And you want to convert this type to this and that.

    Union types allow you to type to take one of the various basic types.

    For example, if developers pass a query that returns either result:string or undefined, we can definitely say that this TypeScript code type needs to be converted to this or that.

    All of these sorts make sense when you think of them as spaces.

How Does TypeScript Differ from JavaScript?

As stated earlier, TypeScript has additional features compared to JavaScript programming language. In simple words, TypeScript is an object-oriented programming language, whereas JavaScript is a scripting language.

This superset of javascript is one programming language bundled up with multiple interfaces and modules through ES6 features; however, JavaScript doesn’t offer such features. In short, Typescript supports interfaces that makes the programming easier.

Moreover, this object-oriented language is strongly-entered, or we can say that TypeScript supports static typing. This means static type checking offers the best accuracy at the time of compilation.

TypeScript highlights the compilation errors at the time of development. Due to this, the scope of examining and getting runtime errors is very low. On the contrary, JavaScript is an interpreted language.

TypeScript is nothing but a superset of javascript and some added features, that is, ES6 features. Therefore, many Javascript developers do not prefer to keep it in their targeted web browser support, but the typescript compiler can compile .ts files into ECMAScript.

TypeScript VS JavaScript: Pros and Cons

Pros and Cons of TypeScript

Pros Cons
It is an object-oriented language that supports strong static typing Unlike JavaScript, TypeScript is not a true statically typed language. In fact, TypeScript is a scripting language that supports dynamic typing.
Easily detect bugs or errors at the compile stage Supports enhanced code readability and code maintainability
With TypeScript, everything stays the way it was initially defined. TypeScript typically requires code compilation at every phase
TypeScript codes are more self-expressive Unit tests are no longer instant
Rich IDE (Integrated Development Environments) support Non-TS libraries require types

Pros and Cons of JavaScript

Pros Cons
just-in-time (JIT) compiled language JavaScript code is viewable to the user, making it used for malicious purposes.
Interoperable: meaning that we can use it with other languages like Node JS, AngularJS, and others and embed it in web pages. The browser interprets JS file differently in different browsers. Thus, the code must be run on various platforms before publishing
Interoperable: meaning that we can use it with other programming languages like Node JS, AngularJS, and others and embed it in web pages. Many HTML editors support debugging, it is not as efficient as other editors like Visual studio code or C/C++ editors. Also, as the browser doesn’t show any error, it is difficult for the experienced Javascript developer to detect the problem.
Versatile, dynamic, and robust scripting language A single code error can stop the rendering of the entire JavaScript code on the website.
Minimizes the code length The continuous conversions take longer in the smooth transition of a number to an integer.

TypeScript vs JavaScript Examples

Here we are bringing TypeScript vs JavaScript examples. Now, we will focus on some code snippets to differentiate between TypeScript and JavaScript.

Have a look at the simple and valid JavaScript code snippet:

let var1 = “Welcome to Albiorix”;
var1 = 30;

Here, we can see that var1 is a string, then becomes a number.

As we know that JavaScript works on the concept that is only a loosely typed programming language, it becomes easy for software developers to redefine var1 as a variable of any type—from a string to a function—at any time.

So, the output of the code becomes 10.

Now, we will convert the same code to TypeScript:

let var1: string = “Welcome to Albiorix”;
var1 = 10;

Likewise, var1 is declared to be a string. And we are trying to assign a number to var1. This is the code structure that is strictly not allowed by TypeScript’s strict type system. Obviously, the transpiling results in an error:

TSError: ⨯ Unable to compile TypeScript:
src/snippet1.ts:2:1 – error TS2322: Type ‘number’ is not assignable to type ‘string’.2 var1 = 10;

If we want to make the same JavaScript code to behave the same like TypeScript, it becomes mandatory to inform transpiler to treat the original JavaScript snippet as if it were TypeScript. So, it becomes the prime responsibility of the transpiler to automatically infer that var1 should be a string | number.

This is a TypeScript union type, which allows us to assign var1 a string or a number at any time. Having resolved the type conflict, our TypeScript code would transpile successfully. Executing it would produce the same result as the JavaScript example.

Validation in TypeScript vs. JavaScript

In JavaScript, validation is typically done using conditional statements and regular expressions. For example, to validate an email address, you might use a regular expression to check if the input matches the format of an email address. If it does not match, you can display an error message to the user. This approach requires careful handling of edge cases and can be error-prone.

In TypeScript, validation is more robust and type-safe due to its static typing feature. TypeScript provides various built-in types such as string, number, boolean, etc., which can be used to define the type of variables and function parameters.

This makes it easier to catch type errors during compilation and prevents them from propagating to runtime. In addition, TypeScript provides interfaces, classes, and decorators that can be used to define custom types and validate their properties.

For example, you can define an interface for an object representing a user and validate its properties as follows:


interface User {
  id: number;
  name: string;
  email: string;

function validateUser(user: User) {
  if (!user.id) {
    throw new Error("User ID is required");
  if (!user.name) {
    throw new Error("User name is required");
  if (!user.email.match(/^[^\s@]+@[^\s@]+\.[^\s@]+$/)) {
    throw new Error("Invalid email address");

const user: User = { id: 1, name: "John Doe", email: "john.doe@example.com" };

In this example, we define an interface User with properties id, name, and email. We then define a function validateUser that takes a User object and checks if its properties are valid. If any property is missing or invalid, the function throws an error. Finally, we create a User object and validate it using the validateUser function.

Overall, while both TypeScript and JavaScript support validation, TypeScript provides a more type-safe and robust approach due to its static typing feature and built-in types.

When to Choose JavaScript and TypeScript?

In the comparison of the difference between JavaScript VS Typescript, it’s time to explore the situation for the fresher or experienced developers to select TypeScript or JavaScript for their project requirements.

You can opt for the TypeScript programming language when

  • Compile Time Type Checking: TypeScript usually supports Vanilla JavaScript, and in such cases, type verification is performed at runtime. It eventually adds to the runtime overhead into the code, which may be avoided by conducting compile-time validation.
  • Large-Scale Projects: As compared to Javascript, TypeScript is a language that is designed explicitly to develop large scale applications that run seamlessly or when many Typescript developers are working together.
  • Easy to Use:If any Javascript developers is involved in React or Node JS development and is not familiar with its APIs, you can utilize IntelliSense, which helps them identify and navigate new interfaces in the newer versions. However, they both offer type definitions.

On the other hand, JavaScript helps you when

  • Small Projects: JavaScript language is a perfect choice if you are dealing with small scale projects or with fewer codes available on the project.
  • Active Framework Support: If TypeScript does not support any common framework like EmberJS or Node JS, then the developers might not be able to leverage all the JS features into the same code.
  • Build Tools:When the professionals need to generate the final run of the JavaScript, TypeScript requires a build step. However, developing JavaScript applications without any build tools is becoming increasingly unusual.
  • Testing Workflow: If JavaScript experts are involved in utilizing test-driven web development project, the benefits of switching to TypeScript may not be enough to justify the expenditures.

TypeScript VS JavaScript: Which is Better?

Selecting TypeScript over JavaScript makes it easy for the developers to deal with removing certain software anomalies during the web development project phase. Moreover, you can easily secure the source code before going into production.

In this article on the difference between TypeScript vs JavaScript, we have seen the overall concept of the available essential features of both technologies. Moreover, we came across the various optional parameters or terminology on how Javascript and Typescript differ.
