• javascript’s competing versions of the languages started emerging. So, JavaScript was eventually taken to ECMA International (Formed in 1961) so that an official standard for the language could be formed.
• Today, the standard versions of JavaScripts are referred as their version number as ECMAScript(ES5 or ES6). Also, it is being referred as their release year as ES2016 or ES2017.
