Should be in this list: https://github.com/jshint/jshint/blob/master/jshint.js#L707-735
I will gladly submit a patch for this.
I don't mind although this list was supposed to represent ES5 and AFAIK none of these globals are in ES5.
Very true. But eventually the standard won't be ES5, it will be ES6. Is your intention to keep them separate?
Good point. I don't really want two separate lists especially since you can blacklist globals thanks to @goatslacker. Are there any other globals that you think should be included?
So far this is safe. There are some that will arrive in time, but they aren't yet concrete. I nominate myself to keep track of this over time :)
Adds Map, Set, WeakMap: standard, members and envs tests. Fixes gh-626
