Same in Python, Rust, Haskell and probably many others.

But apparently JS does work that way, that is its filter always iterates over everything and returns a new array and not some iterator object.

The old methods on Array will eagerly evaluate all elements. But JS has a new Iterator type with methods that works lazily instead.
