What does HackerNews think of firefly?

An alternative BEAM implementation, designed for WebAssembly

Language: Rust

#40 in Compiler
#201 in Hacktoberfest
Add to that GC implementation is different for each language, so having generic garbage collector might not be desirable. Consider Erlang which supports millions of processes per node:

> Each Erlang process has its own stack and heap which are allocated in the same memory block and grow towards each other. When the stack and the heap meet, the garbage collector is triggered and memory is reclaimed. If not enough memory was reclaimed, the heap will grow.

That said, there is a WebAssembly compiler for Erlang:

^ Theres tradeoffs but its certainly interesting.

How long does the fireflyVM, (written in rust,) take to start once it hits the browser?

I think this project used to be called Lumen until pretty recently - https://github.com/GetFirefly/firefly
