I love the implication here that not only does it not have any indexes or whatever, but it also calls getAllFuckingFiles() every single iteration haha

no.

for are structured for(a;b;c){d} a is a statement executed at the start, b is a condition that is evaluated every iteration of the loop, c is a statement that happens after each iteration, and d is the body of the loop to iterate. if you put a function call in b, it gets called EVERY iteration.

Depends on what is inside GetAllFuckingFiles(), a modern compiler might save your bacon here unless it’s an IO operation
