I'm a bit rusty here, does V8 actually do auto-vectorization of JavaScript code these days?

I don't think v8 does any auto-vectorization unless it's been added since 2024 which was the last time I checked.

Thanks! That tracks; ~a year ago I tried fruitlessly to get some numerical stuff to vectorize in Node.js... gave up and switched to WASM SIMD.
