Oh, I guess I'm a stoneager with a penchant for functional elitism then.
Though I will admit OOP is valid for involved data modelling, everything else should be functional though.
I've also trained myself out of most short variable names for maintainability reasons
Outside of the for loop counters i and j, short variable names are awful. Coming back to old code written with abr var nams is like talking to someone in the military who just constantly throws out jargon and acronyms that they know you don't know.
But so are Java style ObserverFactoryManagerTemplateMachinistTemplater names.
There's a sweet middle ground of short, but actually descriptive name. Sometimes it's not possible but that's usually a code organization / language / framework smell.
Too short variable names is usually a sign that you need to use a proper ide, with auto complete, or that you need to use a proper build process that will minify your code after the fact.
Too long names are usually a sign that your module of code (function, class, namespace, etc) is too large, or that your language/framework naming conventions are too strict, or the language doesn't encapsulate scope properly.
I’ve started to prefer writing it out as ”index” or ”iteration” even in for loop counters. It’s easier to read, and not much harder to type.

I is a vowel too but you sure can!
Edit: also I noticed you dropped one 'y' but not the others. Is this an accident or some subtlety to do with y's 'semi-vowel' status? To be discussed.
I had to leave most of first letters, and sometimes if all vowels are removed there's nothing left
But yeah, we need a committee and come up with a standard for that

Keeping things that can be on one line to one line is a good reason to use short variable names where it won't be confusing. Writing "iteration" sounds absolutely perverse!
The thing is, everyone understands i and j. The reason calling variables hcv or iid is dumb is because noone knows what that means - quite a different situation.
I like it to make it clear when the for loop is about iterating lists and when it’s not. For example, the iterations in Monte Carlo algorithms doesn’t correspond to items in a list.
I think even idx is better than just i. I feel like just i can visually get lost
I typically do too, or
userIndexor something for nested loops, but I will accept i and j for the first two levels of nesting when reviewing a PR because they're such a convention. I wouldn't accept variable names like that anywhere else though and try and avoid them myself.
