engine262 VS JS-Interpreter

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.)

JS-based JavaScript interpreter — even though it was a more reassuring option for me (especially with some projects already available in this space), a JS interpreter written in JS simply isn’t a performant solution;

See: #242

Each program is written in JavaScript and interpreted by JS-Interpreter. A step() function of JS-Interpreter is applied to each program alternately.

Here you are, its A JS Interpreter written in JS https://github.com/NeilFraser/JS-Interpreter

Haha, both of those cases are killing both the iframe and the UI. I have to get around to using totally different domain on the iframe to really take advantage of the Chrome process isolation. Previously I was using a really nice JS interpreter written in JS[0] before to solve that problem, but it ran 200 times slower than the browser interpreter(!)

I don't care what current level he is he could Learn and use a "proper" already sanetized interpreter like https://github.com/NeilFraser/JS-Interpreter and implement it by a command sending the result back it demends a real level in Javascript but if he really wants to do it he could. But if you rly wanna drag down someone on his level for no reason go on I am not judge on here and btw I don't advertise I just provide info and links to people / servers whitch did it or here a way to do it. If you are rly that dumb or think you are the only one able to think properly here I invite you to get outta here ;) and as always have a great rest of your day :) I don't consider the invite as advertising taking that taking as point that it is a community server on the subject of this subreadit.
