Hi, does anybody know of a place to determine *what* JavaScript language features can be used (I guess in terms of version--I know there is ES6, ECMAScript 2017, etc), and also *where* can they be used. I'm not just talking of course about what browsers on the desktop<--that used to be the only concern years ago. I'm interested in using the latest and greatest JavaScript that is supported on...
mobile
desktop
Android
iPhone
Windows
Apple
Linux
etc
I tried to find a good resource but failed to find something that covered all areas in terms of device-type, operating system platform, and browser. I know that certain JavaScript engines are used in various places which would help simplify the problem I suppose. Just if you really found something good or know of something I'd be appreciative to hear about it. Thanks.

I stumbled upon this today. Here is an example URL of an online JavaScript reference that DOES give a nice breakdown in matrix-format of what JavaScript is supported and where.
https://developer.mozilla.org/en-US/doc ... ce/Classes
If you scroll down near the bottom of the page you see the support matrix.
