engine262 VS multiview

engine262

Indeed. ECMA-262 has been implemented using JavaScript https://github.com/engine262/engine262.

Node.js is not the only JavaScript runtime. JavaScript runtimes have been written using JavaScript alone, see engine262. There is also Deno, QuickJS, txiki.js, Bun, none of which use COmmonJS by default, SpiderMonkey, et al.

for an interpreted language like JS, this project is really nice https://github.com/engine262/engine262. More or less 2 parts: parser and evaluator

That is a bit complex, so here's a list of JS engines: if you pick one written *in* JS, that would probably be most useful -- engine262 for example

then you might be impressed by https://github.com/engine262/engine262 as well

Engine 262

It's outside of what you asked for, but here's a JavaScript engine in JavaScript. Might make for some interesting bedtime reading!

Interesting to see a JS implementation written in JS:

(The readme explains what the point of it is.)

Multiview, multi-object tracking - https://github.com/prcvlabs/multiview

I started doing research on cameras around 2012 and have been obsessed every since. The company behind this code failed unfortunately but I've kept poking at it and finding more people interested in it, even as my day job is more about cloud infrastructure. Companies like Zippin which have carved out a niche in the cashierless space really impress me.
