Erlang in the Browser

on YouTube ↗34m

" summary

A hobby project implements a tiny Erlang VM in 5,000 lines of JavaScript that runs BEAM opcodes, understands enough of the .beam format to execute code and call into the DOM, and loads modules singly or as a tarball. It links to a normal node over socketjs using Erlang term encoding and can drive common_test across browser nodes. Performance is roughly 10–20x slower and uses about 4x memory, with no hot code loading and incomplete ETS.
