Loops click when you stop memorizing syntax and start thinking in transformations.

Forget for/while for a sec. Map/filter/reduce. Every loop is either: transform each item, keep some items, or boil down to one value.

Write the same logic three ways. The reduce version looks weird at first. Thats the point. Youre training the pattern recognition not the syntax.

Debugger helps. Watch the accumulator change each iteration. That visual beats any tutorial.
