What is array iterator in JavaScript?
The most common iterator in JavaScript is the Array iterator, which returns each value in the associated array in sequence. While it is easy to imagine that all iterators could be expressed as arrays, this is not true. Arrays must be allocated in their entirety, but iterators are consumed only as necessary.
