Javascript introduction:

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

JavaScript was first designed and implemented on the Netscape Navigator browser in 1995 by Brendan Eich of Netscape. Because Netscape was working with Sun, Netscape management wanted it to look like Java, hence the name JavaScript. But in fact its grammatical style is closer to Self and Scheme.

The standard for 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 called ECMAScript 6 or ES2015.
