What is JavaScript?

JavaScript is a scripting or programming language that makes it easy for businesses to implement complex features on web pages smoothly. In simple words, I can say that for every web page visit, it does more than simply displaying static information for you.

What you can do with JavaScript?

  • Displaying timely content updates
  • Creates interactive web pages with integrated maps functionality
  • Performs animated 2D/3D graphics
  • Scrolling video jukeboxes and many more

With its lightweight feature, JavaScript allows you to create more dynamic interactions when developing dynamic web pages, applications, servers, and or even games.

However, you can efficiently use JavaScript alongside HTML and CSS to make your business application more responsive. With the help of JavaScript, implementation of web, mobile application, and game development is much more easier.

Python vs JavaScript: Detailed Comparison

After looking at the basics of Python and Javascript, it’s high time to highlight the difference between Python VS JavaScript in various terminologies.

JavaScript Is Best In Terms of Speed & Performance

Python is a programming language that is well-known for its CPU-intensive tasks. On the other hand, JavaScript works the best for creating web applications and real-time interactions.

JavaScript is solely responsible for enhancing the  speed of business application and also plays a vital role in improving user engagement. And it is made possible with the help of Node.js framework. 

And if I talk about Python, its the best for processing huge data files, CPU-intensive projects, and large-scale applications. And if you’re using Cython or NumPy tools for performing Python source code optimization, it will definitely provide you with the best application performance.

Python Has Gained Huge Popularity

As we are comparing the two big back-end technologies like Python and Javascript, Python and JavaScript are popular one for developers and business owners. In terms of popularity, both technologies are the best, but to be precise, compared to Javascript, Python is the winner.

As per the recent survey by Statista, JavaScript has occupied the 4th position in the most commonly used functional programming language.

Python app development is usually fluctuating with lot of ups and down. And according to the TIOBE Programming Community Index 2022, Python has secured the top position, beating Java, C, and JavaScript.

Apps Developed With JavaScript Language are More Scalable

JavaScript is a programming language that typically supports multithreading features, while Python is a language that allows you to deal with only a single thread at a time.

If you want to build an application for your business that scales well, you should move ahead with Node.js development services. The primary reason behind it is that it is built specifically on JavaScript language. 

Simply put, the applications developed with JavaScript allow you to easily increase the number of threads and scale apps as and when needed. On the other hand, Python actively uses GIL (Global Interpreter Lock), which does not include concurrent programming paradigms support.

Moreover, Python makes it challenging to utilize multiple processors with threads. This simply states that application scaling works best for JavaScript programming language.

JavaScript Has a Steeper Learning Curve

JavaScript is one such programming language that is usually not easy to learn, and thereby I can surely say that it supports a steeper learning curve. But, it’s not the same case with Python language.

In fact, Python is a developer-friendly language and very easy to grasp for any Python developers.

Here, we are talking about the difference between Python and JavaScript; many freshers typically prefer Python as their primary language. Some of the reasons are minimized structural lines, readable code & maintainable code, convert python code blocks, and, most importantly, a quicker development process.

Python Is Built With Feature-Rich Modules & Libraries

Python is a feature-rich and innovative platform that possesses a bundle of modules and libraries. JavaScript does not have many such libraries and modules except a few, like JSON and Math.

Inside the Python language, you’ll find a list of components that enables you to deal with innovative Machine Learning, Data Analytics, data science, and even scientific applications. So, you can just imagine the power of Python programming language using a single Python source code.

And if I talk about JavaScript, only a few pre-configured modules exist. So, this is the major difference between Python vs JavaScript.

JavaScript Makes Web & Mobile App Development Process Smoother

If you’re using JavaScript for developing mobile applications and web apps for your business needs, you’re on the right path. JavaScript helps you perform code faster, work quickly, and, yes, manage a large bunch of data.

Compared to JavaScript, Python usually takes more time for web & mobile app development. As it supports asynchronous programming nature, JavaScript plays a vital role in offering high-end scalability to business applications to a great extent.

It does not mean that Python is not a good option for application development. Python is essential as it is solely responsible for dealing with server-side development. 

However, it provides a stable software development environment with leading frameworks like Django, Pyramid, Flask, and many more.
