05/02/2019, 7:27 PMIt's just a more pragmatic approach to sublists in the context of vectors

05/02/2019, 7:32 PMvectors are basically arrays, but mathematically they are determined by a point, an angle, and a length, and so operations on them in math are based on that length.
so a vector class would be like a list, but its contents would be generated based on a variable length, and you wouldn't be able to alter the contents therein directly. In a perfect world where truly immutable collections existed

05/02/2019, 7:33 PMso if you're doing operations with vectors and you just want to perform arithmetic with a portion of an existing vector, you could use

05/02/2019, 7:34 PMthat's the thought process at least

05/02/2019, 8:05 PMI think some of your assumptions are flawed, but that's neither here nor there.
In computer science, a vector is just another term for a list or an array (they're all roughly synonymous, but each language defines their own nuance around them).

05/02/2019, 8:08 PM...a list, but its contents would be generated based on a variable length...How do you expect to do indexed operations on generated data?

...mathematically [vectors] are determined by a point, an angle, and a length...I think you're confusing representation and definition. That is just a representation of the vector, and it's just as valid to represent it using starting and ending coordinates (and is often quite useful as it allows for easy matrix operations).

05/02/2019, 8:13 PMI don't mean to nit-pick, but I think it is relevant in this case as the difference in method signatures is just that (a choice between representation with magnitude or with end position)
