JavaScript

JavaScript is the most popular language in web development today. JavaScript is used to give interactivity to web pages. It appeared in 1995, but it gained its greatest popularity in the late 2000s, when sites began to widely use its capabilities with the development of AJAX. The latest version is ES 7 (EcmaScript 7) released in summer 2016. A bunch of top frameworks are built on the basis of JavaScript, which are widely used by developers to build fast websites and applications. But to work with them, you still need to learn the basics of JavaScript, so-called Vanilla JavaScript.
