Creaed by Brendan Eich in May of 1995, JavaScript is the most widely used scripting language on earth and has the largest library ecosystem of any programming language. It is the core language of the web, and the only programming language that can run in all major web browsers.
Notably, JavaScript has no relation to Java. [JavaScript: The World's Most Misunderstood Programming Language](http://www.crockford.com/javascript/javascript.html)
The official name of JavaScript is ECMAScript defined under Standard [ECMA-262](https://www.ecma-international.org/publications/standards/Ecma-262.htm)
