Can somebody please help me understand the versions of ECMAScript. I need to make a React JS App using ES7. Now searching in internet there is hell lot of confusion. There is a ES5 version,and then there is EcmaScript2015 which is same as ES6 (I suppose) . So is ES7 another name for ECMAScript2016?
Searching everywhere i only found that react can be written in ES5(createClass) and ES6(class). Are there any syntax differences in ES7?
ECMAScript 7 is old name for ECMAScript 2016 according to the story written by Dr. Axel Rauschmayer
Please take a look to A brief history of ECMAScript
- ECMAScript 1 (June 1997)
- ECMAScript 2 (June 1998)
- ECMAScript 3 (December 1999)
- ECMAScript 4 (abandoned in July 2008)
- ECMAScript 5 (December 2009)
- ECMAScript 5.1 (June 2011
And the best part - ECMAScript 6 (June 2015) history
- ECMAScript Harmony: was the initial code name for JavaScript improvements after ECMAScript 5.
- ECMAScript.next: It became apparent that the plans for Harmony were too ambitious for a single version, so its features were split into two groups: The first group of features had highest priority and was to become the next version after ES5. The code name of that version was ECMAScript.next, to avoid prematurely comitting to a version number, which proved problematic with ES4. The second group of features had time until after ECMAScript.next.
- ECMAScript 6: As ECMAScript.next matured, its code name was dropped and everybody started to call it ECMAScript 6.
- ECMAScript 2015: In late 2014, TC39 decided to change the official name of ECMAScript 6 to ECMAScript 2015, in light of upcoming yearly spec releases. However, given how established the name “ECMAScript 6” already is and how late TC39 changed their minds, I expect that that’s how everybody will continue to refer to that version.
And the grande finale
ECMAScript 2016 was previously called ECMAScript 7. Starting with ES2016, the language standard will see smaller yearly releases.
