My ahead-of-time JS engine Porffor eliminates JS cold starts on AWS Lambda. 12x faster and 2x cheaper than managed Node. Still very early but these results should speak for themselves :) goose.icu/lambda/

This is very cool. Are you imagining use cases outside of cloud / lambda? I have some inkling of an idea of running JS / TS on embedded devices via WASM, but haven’t explored it very much because the existing runtimes seemed prohibitively expensive

Thanks! Yes, there are a surprisingly number of use cases and embedded is a big one like any environment where you can't JIT but want better performance then interpreting. For embedded you can either use Wasm or Porffor's compile to C feature and give that to some proprietary compiler, etc
