— stack[indexZero + index] = value; does ths assignment

—

For reference take does not remove elements from the array, it simply changes an arbitrary length variable in the Proxy and changes what take returns

— Yup index in set is a string

— So it is doing

> 0 + "3"
'03'

— But whyyyyyyyyy

— That's JS, I guess.

Same thing with:

> "5" - 3
2

— Well I wonder why it is casting index to string...

— Like, before set can get it

— This fixes it

—

stack[indexZero + Number(index)] = value;

— I feel like this is actually... a bug

— In JS
