Should single-use functions be named?

I actually mean lambdas and IIFE's.

Also, should they be local, especially if they are very small?

If the name adds useful nuance which is not obvious from the implementation, then by all means.

if it's more than 1 line of code yes, if it's just a 1 liner like regex and lambdas then it should be ok to not name it. But it should clear for anyone who comes in to maintain your code.

Imo If they are inline its fine not to name them.
