Typed array iterators

The [Symbol.iterator]() method of TypedArray instances implements the iterable protocol and allows typed arrays to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns an array iterator object that yields the value of each index in the typed array.

The initial value of this property is the same function object as the initial value of the TypedArray.prototype.values property.
