NQP implements a subset of Perl 6 that is useful for writing a compiler, and that runs well on parrot without the need for built-in functions (except the regex engine).
How exactly is this entire bootstrapping done?

Since NQP transforms its input to a format called PAST, the first step will probably be to write a PAST compiler that emit JS. Since the PAST compiler is now written in PIR, the bootstrapping plan might look like this:

  1. Re-write the PAST compiler in NQP
  2. Add a variant of the PAST compiler that emits JS
  3. Run the NQP-on-parrot on itself, emitting javascript
  4. reiterate until it works
  5. Profit!
