I think a little history lesson is due.
However, Eich decided that Java, with all its rules, was too complicated, so he set about creating a simpler language that even beginners could code into. This shows in things like easing the need to have a semicolon.
ECMAScript had a couple of releases and in 1999 they released their last version (ECMAScript 3) before going into hibernation for the next 10 years. During those 10 years Microsoft dominated the scenes but at the same time they didn't improve their product and so Firefox was born (led by Eich) and a whole host of other browsers like Chrome, Opera.
ECMAScript released its 5th edition in 2009 (4th edition was abandoned) with features like strict mode. Since then, ECMAScript has gained a lot of momentum and is expected to be releasing its 6th edition in a few months with the biggest changes it has had so far.
A list of the functions for ECMAScript 6 can be found here http://kangax.github.io/es5-compat-table/es6/ as well as the browser support. You can even start writing Ecmascript 6 like you did with CoffeeScript and use a compiler to compile up to Ecmascript 5.
There are also other flashy languages that implement ECMAScript, such as: B. ActionScript (used for Flash).
ECMAScript = ES:
ECMAScript is a standard for scripting languages.
ECMA stands for European Computer Manufacturer's Association
ActionScript and JScript are other languages that implement ECMAScript.
ES5 = ECMAScript 5:
ES5 is a version of the ECMAScript (old / current).
ES5 doesn't require a build step (transpiler) to turn it into something that runs in today's browsers.
ECMAScript version 5 was completed in December 2009. The latest versions of all popular browsers (Chrome, Safari, Firefox and IE) have version 5 implemented.
Version 5.1 was completed in June 2011.
ES6 = ECMAScript 6 = ES2015 = ECMAScript 2015:
ES2015 is a version of the ECMAScript (new / future).
Officially, the name ES2015 should be used instead of ES6.
ES6 will address many of the core language shortcomings addressed in TypeScript and CoffeeScript.
There are some transpilers that export ES5 to run in browsers.
BabelJS just takes the ES2015 file and converts it to an ES5 file.
TypeScript and CoffeeScript:
The ECMAScript® language specification defines all the logic for creating and editing objects, arrays, numbers, etc.
DOM ( D. OKUMENT O bject M. odel) makes it possible to (e.g. communicate) with HTML / XML documents.
BOM ( B. rower O bject M. odel) is the hierarchy of the browser objects (e.g. location object, history object, form elements).
What is ECMAScript ie ES?
DOM API like:
Do other languages use the ECMAScript standard?
- ActionScript (used by Adobe Flash) and JScript (used by Microsoft) are both languages that implement the ECMAScript standard.
Why is it called ECMAScript?
I know this is an old post but hopefully this will help someone.
Existing answers describe the main point quite well.
The main point is that ECMAScript is the mere abstract language with no domain specific extensions, it is useless in and of itself. The specification only defines the language and the core objects of it.
There are many ECMAScript engines, some of which are open source and some are proprietary. You can link them to your program and then add your native functions to the global object to make your program scriptable. Although they are mostly used in browsers.
Implementations have other names like V8 or Rhino etc.
ECMAScript is a standard for JavaScrip . Check out these instructions from MDN :

Here are my results:
A blog post from Microsoft seems to coincide with what Flanagan explains with the words.
.. which makes me think that all occurrences in this reference post (again from Microsoft) need to be replaced by. They actually seem to be wary of just using this newer and more technical documentation page.
w3schools.com seems to agree with the definitions above:
The key here is: the official name of the language .
When you see the latest release notes, you will always see references to ECMAScript standards such as:
The ES2015 Symbol.toStringTag property has been implemented (bug 1114580).
The ES2015 TypedArray.prototype.toString () and TypedArray.prototype.toLocaleString () methods have been implemented (error 1121938).
Don't forget that ActionScript used in Adobe Flash / Flex is another popular language that revolves around the ECMA scripting standard.
