The closure compiler is also pretty slow, a way around it is to keep a warm jvm and compile that way (70% performance increase over time). I assume a similar strategy is not possible for typescript, which is a pity.

Typescript seems pretty cool, lack of dead code analysis and the inability to write my own compiler passes (I have looked for this, but it does not seem to be an option - would love to stand corrected) puts me off it.
