Best thing: using pad-left as proof the JS' problem is that the committee can't add basic shit to stdlib: https://github.com/tc39/proposal-string-pad-start-end … (stage 3!)
@ljharb @awbjs @thejameskyle @bterlson that said, for a simple enough, easy-to-desugar feature with no concrete impl concerns, YOLO

@ljharb@awbjs@thejameskyle as@bterlson said in the last meeting, tons of "real engine" Chakra impls are polyfills. -
@wycats@ljharb@thejameskyle@bterlson self-hosted impl in “real engines” is fine as long as match spec and passes tests

@wycats@ljharb@thejameskyle@bterlson If something is simple enough+important enough getting quick browsers imply shouldn't be hard. -
@awbjs@wycats@thejameskyle@bterlson not hard, but slow. and finding people + time is hard too. -
@ljharb@wycats@thejameskyle@bterlson If “real engines” don’t impl quickly, that’s a smell that needs to be considered. -
@awbjs@ljharb@thejameskyle@bterlson I'm just not sure what a "real engine" is. Hard to find analogies with C++ stds that make sense -
@wycats Full from-scratch implementations encounter different sorts of challenges from transpilers and libraries and give valuable feedback
