Node JS is JavaScript runtime which let's you run JavaScript outside of the browser. Node runs JS programs with Chrome's V8 engine. Nodejs is useful as most of the web developer (front end) know JavaScript and Node help them to write back end code as well with JavaScript. Which means you don't have to learn new language for backend. And then it's capable of running asynchronous tasks which gives the maximum performance. So it's quite popular.
