A tool for making JavaScript code run faster
Even though I'don't like Facebook as a user, their amazing contributions to open source are something to be very grateful for. Last week they presented their new work in progress: Prepack.
Prepack is a tool that optimizes JavaScript source code: Computations that can be done at compile-time instead of run-time get eliminated. Prepack replaces the global code of a JavaScript bundle with equivalent code that is a simple sequence of assignments. This gets rid of most intermediate computations and object allocations.
It's still in development, so best not use it in production environments yet.
