Bugs?

Now you may say "wait, wait, wait!" This optimizes on things that aren't just arrays! My map#forEach is optimized too! To fix this, add a comment that says // O: KEEP right before the line on which you use the forEach. Examples:

var m = new Map();
// O: KEEP
m.forEach(f)

or:

var s = new Set();
// O: KEEP
for (var i = 0; i < 5; s.forEach(f)) {
    // ...
}

This is required since it is not possible to determine an object's type at compile-time.

Example

1function timesTwo(arr) {
2	return arr.map(n => n * 2);
3}

to:

1function timesTwo(arr) {
2    var _a = arr;
3    var _f = n => n * 2;
4    var _r = [];
5
6    for (var _i = 0; _i < _a.length; _i++)
7        _r.push(_f(_a[_i], _i, _a));
8
9    return _r;
10}
