Some thoughts

To be really more useful than a exotic dialect of Perl you will need to implement eval too, since recompiling is the core of all require and use code.

This means you'll also need to transpile your PPI-version.

You might also be interested in Flavio Glock's work running Perl under JS and Java, IIRC he's still onto it and gave a talk at last LPW.

HaukeX's WebPerl already does that at roughly half speed. Using a hypothetical B::Deparse2JS could be used to speed up time consuming sub-routines (in a kind of JIT/afterburner way).

My issue with WebPerl was that it's memory intensive and slow to start-up°, but I haven't looked into it since before the pandemic.

°) well maybe it's possible to hide this behind a web worker. And local caching in the browser would be a plus too.
