javascript introduction:

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

JavaScript was first designed and implemented in Netscape Navigator in 1995 by Brendan Eich of Netscape. Because Netscape worked with Sun, Netscape management wanted it to look like Java, hence the name JavaScript. In fact, it is similar to Self and Scheme.

JavaScript is ECMAScript. As of 2012, all browsers fully support ECMAScript 5.1, with older versions supporting at least ECMAScript 3. On June 17, 2015, ECMA International released the sixth edition of ECMAScript, officially known as ECMAScript 2015, but commonly referred to as ECMAScript 6 or ES2015.
