Also my issues with TS are: 1) what if future ECMA will bring incompatible changes with current TS ? TS will break compatibility or we will have another EEE from MS ? Dart clean break seems like a safer approach. 2) there is no cross-platform IDE for TS (yea I know plugins - but Dart has stock cross-platform IDE) 3) TS perf will be always as good as JS

What's library hell in JavaScript? I've never heard anyone use that term ever.

Any links for the perf issues you mentioned? There's some massive JS apps at Walmart and PayPal.

I mean there are many incompatible libs, module and import methods in JS
