I think pointers are pretty fundamental in programming, so understanding them might be a good idea even if you don't use them NOW (and it's a pretty basic concept tbh). You can't be sure you'd be writing JS (or any other language without pointers being present to the programmer) for life. I thought that I won't face them, but then I've started programming in Golang and here we go.
I'd suggest to learn as much as you can because every day it gets harder for your brain to learn, memorize and understand information.
