It's not an anti pattern. It's actually a zero cost abstraction. Iteration using recursion causes the stack to fill up. You could say reduce can work but ultimately reduce needs to be implemented using recursion or a for loop. Reduce is a higher level function and therefore not part of the argument. That being said I do know about Tail recursive optimization. Most language implementations do not support that though.
