Remove array element within function

[Rekel]

Ah, ref, thanks, I didn't know if that would work as I was 
confused since arrays themselves are kind of already pointers.

I believe for setting length it was both when I wanted to 
initialize the array to a certain length (instead of having that 
inline with the declaration) & when I want to clear the array of 
all data. Though I also found threads in which people mentioned 
changing the length manually after calling remove.

The copies were mostly at play in scenarios such as this one, but 
also when I'm appending lists to lists, in a 
`list.addAll(list2);` scenario. Though I guess I'm just not used 
to reassigning on the list variable after doing things with it.

Also, is my use of long correct? The documentation wasn't very 
clear on the return type of remove, just calling it a 'number'.

Again thanks for your help 😅
