Fully agree - if you have the full function or scope of the variable in sight, keeping the variable short make it easy to read and quick to type. Of course if you program in something like k or goal, almost everything is single letter (:
replied to:To never use single character variable names. I think a variable nameโs length should reflect its scope โ a function thatโs only a few lines long can use single letters no problem.
