JavaScript is the most popular programming language in the IT world. JavaScript is among the most powerful and flexible programming languages on the web. It powers the dynamic behavior on most websites, including this one. JavaScript is a Scripting language.

JavaScript allows you to create highly responsive interfaces that improve the user experience and provide dynamic functionality without waiting for the server to react and show another page.

Netflix initially used Node.js to enable high-volume web streaming to over 182 million subscribers. The user interface of Netflix was built using node. Js. According to the Netflix team, the modularity of the Framework encouraged them to use Node Js. Node JS is a server-side JavaScript runtime that allows developers to write the same code for both the front end and back end of a web application. Node also improves the build times considerably.
