WinterJS 1.0 Runtime (written in Rust, using Spidermonkey)

There is some comparison of Winter vs Node, Bun, and Deno. But not much.

I’m curious what they are going to do here. I could imagine… but I always come up with something slower unless it pre-compiling startup code. Otherwise I think the JS engine will be better. Unless you don’t want the JS engine at all…

Their use of SpiderMonkey does remind me though, that Firefox used to recompile extensions for next startup. I wonder if they still do that. That was before Electrolysis.
