Re: Compiling JS to luajit bytecode: CASTL

[Tim Caswell <tim@...>]

I wonder how it compares to the code tessel.io is using to run node on embedded hardware.  I talked to them at their booth at jsconf and they are running elua on the metal and compile the js to lua bytecode.

Hello Karel,

Thank you for your small review! Yes we're far from V8, the overhead to imitate JS behavior is actually too high... but CASTL is more a proof of concept, for science :) And as you said it could be useful in some embedded systems.

Small review:

It is self-hosting and able to compile large hunks
of code [1]. While performance seems to be nowhere near V8 (w/ LuaJIT, will
post benchmarks once I'm done porting stuff to this), it will prove very
useful in places where carrying humongous V8 around is not an option.

Very impressive Paul, thanks!
