What is the purpose of Node.js and why is it so useful?

Node.js is a runtime environment that executes JavaScript code outside a web browser. It is designed to build scalable network applications and is particularly useful for server-side applications.

Node.js is built on top of the V8 JavaScript engine, the same JavaScript engine that powers the Google Chrome web browser. This makes it a very fast and efficient platform for executing JavaScript code.

One of the main advantages of Node.js is its ability to handle a large number of simultaneous connections with high throughput. This makes it well-suited for real-time applications such as chat, stock tickers, and online games.

Node.js also has a large and active developer community, which has contributed a large number of packages (libraries of code that can be used to build applications) to the npm (Node Package Manager) repository. This makes it easy to find and use packages to build applications, and also makes it easy to share your own packages with the community.

Overall, Node.js is a powerful and useful platform for building network applications and is used by many companies and organizations around the world.
