What is JavaScript?

JavaScript (JS for short) is a lightweight, interpretive or just-in-time programming language with function priority. Although it is known as a scripting language for developing Web pages, it is also used in many non-browser environments. JavaScript is based on prototype programming, multi-paradigm dynamic scripting language, and supports object-oriented, imperative, declarative, and functional programming paradigms.

JavaScript was first designed and implemented in Netscape Navigator browser by Brendan Eich of Netscape in 1995. Because Netscape works with Sun, Netscape management wants it to look like Java, so it is named JavaScript. But in fact, its grammar style is similar to that of Self and Scheme.

The standard of JavaScript is ECMAScript. As of 2012, all browsers fully support ECMAScript 5.1, and older browsers support at least the ECMAScript 3 standard. On June 17, 2015, ECMA International released the sixth edition of ECMAScript, which is officially called ECMAScript 2015, but is often referred to as ECMAScript 6 or ES2015.
