that actually seems really inefficient, it could avoid the array allocation and fill call by just moving the length check...

You could also just use `String.prototype.padStart()` [1], and you get a nice optimized C++ implementation :D

Pass, not a Rust implementation /s

Is it even AI scale if not performed on the GPU?

No, you're right. The White House says no more C/C++ it's your civic duty.

While funny, worth remembering that .padStart didn't exist when left-pad was first published :)

While it's not quite C++, here is Chromium's implementation: https://source.chromium.org/chromium/chromium/src/+/main:v8/...

It's Torque, which is essentially C++
