Comment by Gergely Polonkai on "Do you prefer variables like "event" instead of "e", or "index" instead of "i"?" | Hashnode

You have to believe in things that are not true. How else would they become?

I usually go the middle route: idx and evt.

They are still short enough not to type much when using them, but long enough to be obvious and not to freak out linters that require a minimum identifier name length.

Hmm, idx has actually tripped me up before when looking at someone else's code. In my head I read this as "id x", and took me a while to figure out it was the index. I feel like if there is a reason to shorten variables, i would be more descriptive as it is more common. However, since you're already making it slightly longer, why not just name it index?

Because that’s too long, especially if you have to write it many times.

Also for “ID [of] x” I prefer x_id instead.
