Allow ECMAScipt 6 syntax on PlayCanvas projects

Since the release of Firefox 57 and Chrome 62, ECMAScript 6 has been now the new Browser JS syntax. It may be nice if we can enable ECMAScript 6 for projects as this would introduce more cleaner code project-wise.

ECMAScript 6 Syntax list

hmm idk but play canvas uses es5 not sure about ES6
but you can look at these links

You can use ES6 just fine in your PlayCanvas project. You’ll just get warning symbols in the margin because your code won’t work in browsers like IE11, for example. If you don’t care about that, you could hide the warnings by adding the following to the top of your script file:

/*jshint esversion: 6 */
