Hi! Judging from the comments only this looks to be a great tool. Good job!

I'm a developer currently learning more backend and JS. I hope this question doesn't come out as arrogant. I heard once that "a good compiler should be able to compile itself". Does prepack prepack itself to run faster or can it just for the fun of it? :-)

Not quite. This PR is almost ready to do it.

https://github.com/facebook/prepack/pull/397

Currently it is blocked on Map/Set support in the output which is an outstanding issue. We could also try it with a Map/Set polyfill.

We're very close to being able to though!

In fact, this isn't just Prepack itself but it is Prepacking the JS part of the entire Node.js runtime as well!
