ES vs JS
If you cant answer the following questions, this post is for you
1. Do you code in ES or JS?
2. What does ES stands for?
Not until 2009 did Microsoft came up with IE 8 which conformed to the standard. Before this people had to watch out for IE specific issues and had to write extra code just to support IE as its market share was still high.
As of now there have been 10 editions of ES. ES1 to ES9 including ES5.1(Incremental to ES5) and ES4(Abandoned). The latest is ES9 which obviously has a lot of features which will take time to get implemented by browsers. ES5 is the version that is mostly supported by browsers as of now but ES6 is slowly moving in with newer browsers such as chrome.
Coming back to our questions at the top.
#2 As given above ES refers to ECMAScript which means European Computers Manufacturing Association.
#4 ES9 is the latest, ES5 is mostly used, ES6 has a lot of new features.
