ECMAScript is a general-purpose programming language that is implemented in JavaScript and some other languages. It is the scripting language that formed the basis of browser-based JavaScript and Node.js. ECMA is an acronym for European Computer Manufacturer’s Association, which develops standards for information technology and consumer electronics. Languages such as ECMAScript, Dart-lang, and C# were standardized by ECMA.

Think of ECMAScript as Javascript without a host environment. Javascript has two major environments: browsers and Node.js. These environments add some APIs to the language. An example is the window object on Browsers and the fs module in Node.js. If you strip all external APIs from these environments, you get ECMAScript.

ECMAScript is a standard. While JavaScript is the most popular implementation of that standard. JavaScript implements ECMAScript and builds on top of it. ES is simply short for ECMAScript. Every time you see ES followed by a number, it is referencing an edition of ECMAScript.

ECMAScript , has brought about a ton of changes to the JavaScript programming language. In this course, you'll explore some of those changes to learn about the latest features and improvements to the language including new keywords, arrow functions, the Class syntax, Promises, and so much more.

This course will cover some ECMAScript features from 1997 -2018
