I believe index for the classical need to iterate through an array. E.g.
for (i = 0; I <= arr.length; i++) {
var thing = arr[i]
…
}
So to me it stands for “index” for array lookup.
Before map and iterators were implemented in a lot of languages, this was the defacto way to iterate a list. At least this is how I learned it in java/c back in the day. Nowadays I think most OOP languages including java have implemented the “for … in …” Syntax or similar which deprecates this convention.
Is it for “index” or “iterator”?
yes
index and jindex
