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 :)

If you have AWS Lambdas with a small amount of (Node)JS please DM me :)

Porffor now passes over 60% of Test262, thanks to a new custom regex engine!

Porffor now has its own fuzzer which abuses the compiler with randomly generated JS code in an attempt to find bugs which would otherwise not be found to help stability!

Porffor's Wasm is now faster than *native* Node JITless at richards.js, an old V8 benchmark!
new improvement is thanks to a new compiler feature and a minor object rewrite I'll post about this weekend. I still have ideas which can make this hopefully almost 2x faster this month!

just had a great catch up with @goose.icu on porffor progress. keep an eye on this project 👀 there's so many perf gains to be had from it once it is stable

Porffor now supports BigInt typed arrays: just this (plus some related changes) boosts Test262 passing by over 0.7%!
![A Porffor JS REPL:

Porffor now passes over 57% of Test262! This latest bump was thanks to a refactor makes functions and methods distinct to be more conformant for this, construction, etc

I love @goose.icu's Porffor Test262 compatibility plot, I'd love to make one for @convex.dev's JS Runtime (so for runtime features, not languages features)

this gave me an idea... decorating typescript functions to just in time compile and execute them in web assembly with Porffor.
it works!!

I'll be here and in Seattle that week for TC39! :)
This is going to be an extra special SeattleJS event.
We’ve got some amazing speakers from TC39, the committee who makes JavaScript, giving talks about the future of the language!
Docusign has a great setup for this AND they’re providing food and drinks!
You don’t want to miss this one.

I rewrote Porffor's object implementation completely; it is now much faster and makes Wasm binaries 2-5x smaller than before when using objects!
Porffor's current worst benchmark gets 30% faster with >4x smaller Wasm; almost on par with QuickJS with only ~1 month of work!

I’ve been helping (alongside others) to Champion Temporal for around 6 years now, it’s great to see it approaching the finish line. The responses have been positive.
Great work @joshcena.com and @meyerweb.com on the MDN documentation, momentous effort. Also props to the main man @ptomato.name
