However, Node.js addresses this issue using event-driven programming, allowing it to handle multiple requests using asynchronous code.
• Callback hell: Node.js uses callbacks extensively, which can lead to a situation known as “callback hell.” This occurs when JS code becomes nested and difficult to read due to multiple callback functions. However, developers can mitigate this issue using other patterns, such as promises or async/await.
• Performance issues with CPU-intensive tasks: Node.js is optimized for I/O operations and may not perform as well with CPU-intensive tasks. This is because Node.js uses a single thread to handle requests, and CPU-intensive tasks can block the event loop, causing delays and slowing down the application. However, developers can mitigate this issue by using worker threads or offloading CPU-intensive tasks to separate processes.
• Lack of built-in support for some features: Node.js is a relatively young technology, and it may need more built-in support for some features that other languages and platforms provide. However, developers can often find third-party modules or libraries that provide the required functionality.
• Security concerns: Node.js has potential security issues due to its reliance on third-party modules and libraries. Developers should ensure they use trusted and up-to-date packages and implement security measures such as input validation and authentication.

Overall, Node.js is a powerful and versatile tool, but developers should be aware of its potential drawbacks and use it appropriately for their specific use case.
