How fast is it compared to CoffeScript compile

[basarat]

Just curious if you've compared. Basically does it do semantic validation? Could we switch that off and just do the syntactic one (needed for valid emit).

@basarat This is simple benchmark of typescript-simple vs. coffee-script
https://gist.github.com/teppeis/68baae014137778b76c4

For 200 times compilation of tiny equivalent code, typescript-simple is 60% slower than coffee-script.

• typescript-simple 1264ms
• coffee-script 798ms

but typescript-simple requires additional 500ms for warm up at first time.

Sure! typescript-simple checks semantics (static typing) and throws an error if it's invalid.
But I cannot find the way to switch that off in TypeScript 1.4 Compiler API.
