What are the main advantages and disadvantages of using Node.js in server-side application development?

Advantages of Node.js:

• Asynchronous and event-driven model: Allows efficient handling of multiple concurrent connections without blocking.
• Single language on client and server: JavaScript is used on both the frontend and backend, simplifying development.
• Large npm ecosystem: Many ready-made modules and libraries.
• High performance for I/O tasks: Especially suitable for applications with a large number of network requests.

Disadvantages of Node.js:

• Single-threaded model: Heavy computations can block the event loop and reduce performance.
• Not always suitable for CPU-intensive tasks: For example, complex mathematical calculations are better performed in other environments.
• Young ecosystem: Although npm is vast, the quality of some packages can vary.
• Error handling: Requires careful approach to asynchronous code to avoid missing exceptions.
