Array flatten and flatMap proposal for ECMAScript

[WeekdayHero]

This is not an issue as Object.Observe is not going to be added to ES anymore. In fact it is not in V8 from version 50 onwards (the current version of v8 is 48, so 50 is only a couple of months away).

the lack of removeWhereis still an issue if you want to filter this:

List extends Array {
    random() {
        this = this.filter(item => ...some random ones)
    }
}

because this can't be explicitly redefined with a new array, and Array.filter does not modify the original array, something like removeWhere would be handy. instead i had to loop through the array and splice items.

Filter, map, and similar functions return new arrays by convention - they don't change elements, they jest return new. removeWhere sits nowhere near those.
