Absolutely. Compilers do *not* have to be integrated in with parrot -- my current work project uses Parrot as its back end, but the compiler's written in perl as a standalone program. Works just fine. (Though a Javascript compiler written in Javascript could bootstrap itself pretty nicely. That'd be cool... :)
Though integration with the parrot compiler system would be very useful, both for writing browsers and similar in parrot, and for implementing javascript's eval() builtin.
That could well come quite a bit later, though -- after you can bootstrap yourself into PIR, for example. (Either with yourself, or compiling whatever other language you're written in into PBC.)
