Stuff I've learned about WASM and WASI

WASM and WASI Notes

Web Assembly can make use of OS capabilities with the Web Assembly System Interface. It allows calls to OS functionality like clock, fs, network etc.

Spec

  • WASM is the fourth W3C web standard next to HTML, CSS and JS
  • WASI is an additional spec that standardizes how Web Assembly can do more than just run in a sandboxed environment but interact with system resources.
