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.
