One place where nesting makes things difficult is in error handling. If at each potential error point you best one level, you quickly find yourself deeply nested. I find the pattern of exiting early and having the “happy path” running to the end of the scope to make it much easier to comprehend a function (I’m sure there’s a term for this coding style but I can’t find the name of it at the moment).
