#2This is super cool, I didn't know JavaScriptCore consistently outperformed V8
And SpiderMonkey seems... not up there compared to the other 2
Re: JavaScript engines zoo – Compare every JavaScript engine
#3Is this right? Brimstone has a single contributor, 74k LoC (vs 1.3M for V8) and it's 97% compatible with ES6?
That's a staggering accomplishment.

Disappointing for Firefox for such lower performance.
I just ran the JetStream2 benchmark and got:
- Firefox: 159 score
- Chromium: 235 score
That's on latest Fedora Linux and Ryzen 3600 CPU.

#5That's a lot of duplicate code. Différent hardware constraints and history I guess.
Re: JavaScript engines zoo – Compare every JavaScript engine
#6I assume the 98% compatibility on ES6 for V8 is because they don't have tail call optimisation?

Interesting how V8 to JSC ~2x LOC but ~2/3 the binary size.

Pretty much. ES6+ scores are from running compat-table's test suite (https://compat-table.github.io/compat-table/es6/), along with their weighting. If you click on an engine's name to go to a page about it, there's a report at the bottom with failing tests.

Maybe because with tail call optimization you wouldn't have a proper stack trace?
