Symbol.iterator — strings are iterable

📖 Usage Example

typeof ''[Symbol.iterator]   // → 'function'
[...'abc']                   // → ['a', 'b', 'c']

Strings implement Symbol.iterator, allowing them to be spread into individual characters.

String Symbol.iterator

Strings also have a Symbol.iterator method.

Challenge: Verify that ''[Symbol.iterator] is a function.
