porffor is a new ahead-of-time compiler for javascript

juicy numbers (output size, mean runtime, mean rss)

• hi_bun 97M 55ms 75MB
• hi_deno 100M 16ms 31MB
• hi_porffor 20K <1ms 1.4MB
• hi_javy 1.3M - - (javy is a js to wasm compiler)
• hi_porffor_wasm 4.0K - -
• no benchmark demo for the last two bc wasm is hard to run server-side (for now)
• no benchmark demo for quickjs, another ahead-of-time compiler?

github canadahonk/porffor

• porffor is completely written in ts/js, for better or worse

current limitations

• with is a no-op for now
• eval is unsupported for now - it’s possible but annoying to impl
• takes advantage typescript type annotations
• no gc or fancy allocator - best for short-running use cases like aws lambda

impl challenges

• things that are inexplicably underspecified, like Date.parse() or Array#sort()
• runtime code evaulation (as above) - would need to ship a mini engine in output
• optimising prototypes without breaking shit
