Node Js is a server-side JavaScript interpreter that allows JavaScript to operate outside a web browser. It is based on the V8 JavaScript engine that was designed by Google for its Chrome browser. Node Js is extremely adored for its non-blocking model of I/O event-driven which makes it easy for the framework to handle multiple connections concurrently and not block the main thread. This makes the data structure ideal for use in applications where there is a need for updating the data frequently such as in chat and online gaming as well as streaming platforms. This article will provide an introduction to node js, including its key features, advantages, disadvantages, and common use cases.
Key features of Node JS
Asynchronous programming: Node js works asynchronously or you could also say it adopts an event-driven model of programming which makes it capable of performing multiple tasks at once without hindering the main thread. This enhances performance and scalability.
Event-driven I/O: Node js is built on the concept of an event-driven I/O model, where callbacks are invoked when I/O operations are done. This makes it possible to handle several concurrent requests.
