Node JS is designed to construct quick and scalable network applications and is built on Chrome's Javascript runtime. It makes use of server-based, event-driven, lightweight, and effective applications that are spread across the systems. To manage HTTP requests and provide content, Javascript is employed. A user may even write the logic in JavaScript on the server when creating complex client-side applications in JavaScript so that mental translations between the two languages are possible.

Web Servers

A web server can be built using Node JS. Node JS has the benefit of being event-driven and not waiting for the outcome of a prior call. It switches to the subsequent call while utilising events to receive notifications when a response is received for the preceding call. The Node JS-based servers are extremely quick, don't use buffering, and transport data in chunks. Additionally, it utilises an event loop that is single threaded and non-blocking. The createServer() method of the HTTP module can be used to assist in the creation of a server. Every time someone tries to access port 8080, this procedure is run.
