History (wikipedia)
JavaScript was originally developed in 10 days by Brendan Eich of Netscape under the name Mocha, later LiveScript, and finally renamed to JavaScript (1996).
Netscape delivered JavaScript to Ecma International for standardization. The first edition of ECMA-262 (“ES1”) was adopted in 1997.
The name “ECMAScript” was a compromise between the organizations involved in standardizing the language.
The official name of the latest JavaScript version is ECMAScript 2015 (a.k.a. ES6); it was released in July 2015.
As of early 2016, no browser fully supports ES6. To run ES6 in a browser, a transpiler (syntax transformer) is required.
We will use Babel, Webpack and npm to learn the basics of ES6.
