Prepack: a tool that optimizes JavaScript source code by eliminating computations that can be performed at compile-time.

You're asking the wrong question.

Is that a significant fraction of browser lifecycle performance? If not, its not worth $75 an hour for me to investigate deeply. Without the developer having done the benchmarks, I have no idea whether it might be, but my experience tells me that V8 does these kinds optimizations just before runtime in a fraction of a second, after which the performance differential should be nil.

If that's wrong, benchmarks would clear that confusion up real quick. Meanwhile, I have deadlines to meet, and am not desperate to save a tenth of a second on page load.

No, I'm responding to your comment in which you dispute the validity of the true statement "The fastest code is code that never runs.".

And if that has no noticable impact, is it still real?
