It looks like an array, but unfortunately, it isnt :(
Actually, maybe I should write a post about that. The arguments is an interesting topic and I don't think everyone knows that exists 🤔 Even if they knew, the post will be a nice reminder 😂
@samanthaming
if you end up writing a post on it, I beg of you to include warnings about performance and analysis implications, as well as the "single rest argument"((...args)) alternative.
Honestly, that's the only way I see to offset the damage of more people finding out about/remembering it :D
AFAIK it causes deoptimization, while (...args) works much better.
Still, if you expect a real array, like in Math's case, you should just take an array.
Good ol' this.arguments. My favorite Javascript feature that I'm afraid to use because it doesn't have all the Array methods I want.

These both fail with a stack overflow, and the only way to get an answer is to implement it yourself:
