    What is Node.js?

    Node.js is a platform built on Chrome's V8 JavaScript engine that allows developers to build scalable and high-performance applications. It uses an event-driven, non-blocking I/O model, which makes it perfect for applications that require real-time communication or need to handle a large number of concurrent connections.

    Node.js is often used for building server-side applications, but it can also be used for developing desktop and mobile applications. It provides a rich set of built-in modules, making it easy to work with file systems, networking, and other commonly used functionalities.

    Why is Node.js popular?

    • High Performance: Node.js uses a non-blocking, event-driven architecture that allows it to handle a large number of concurrent connections without consuming excessive system resources.
    • Scalability: Node.js applications can easily scale horizontally, allowing developers to add more servers to handle increased traffic.
    • Real-time Communication: Node.js is perfect for building applications that require real-time communication, such as chat applications or collaborative tools.
    • Large Ecosystem: Node.js has a large and active community of developers, which has resulted in a vast library of open-source modules and frameworks that can be used to accelerate development.
    • JavaScript: Node.js uses JavaScript, which is one of the most widely used programming languages. This makes it easy for developers to switch from front-end to back-end development.

    Overall, Node.js offers a unique combination of high performance, scalability, and ease of development, making it a popular choice for building modern web applications.
