I like the most about it's asynchronous I/O operations using libuv library written in C. It's highly efficient and easy to write I/O intensive applications.

Node.js allows for multi-stack development, enabling the creation of both frontend and backend applications. Setting up Node.js is straightforward, and in my years of experience, I have used it for building both frontend web apps and backend servers. It allows developers to use JavaScript for both client-side and server-side scripting. With its event-driven architecture and non-blocking I/O operations, Node.js is ideal for applications like chat apps, gaming servers, and collaborative tools that require constant updates. Node.js is well-suited for building RESTful APIs and microservices. Its lightweight and fast nature, combined with the extensive ecosystem of NPM (Node Package Manager), makes it easy to develop and maintain scalable and performant APIs. Node.js can be easily integrated into web apps, servers, and lambda functions. Many frameworks are built upon Node.js, enhancing its versatility. In my experience, I have completed numerous projects using Node.js. Its asynchronous nature allows it to handle a large number of concurrent connections with minimal resource consumption. The Node.js community is continually growing. With lot of open-source projects, tutorials, and resources available, developers can quickly find support and solutions to common problems. This active community also contributes to the rapid evolution and improvement of Node.js.

It's wide application and range of community support. I am a web developer since last 3 years and node has been my go to development env due to its easy nature.
