The toArray() method of Iterator instances creates a new Array instance populated with the elements yielded from the iterator.

The filter() method of Iterator instances returns a new iterator helper object that yields only those elements of the iterator for which the provided callback function returns true.

Swaps the values at two mutable locations of the same type, without deinitializing either.

The reduce() method of Iterator instances is similar to Array.prototype.reduce: it executes a user-supplied "reducer" callback function on each element produced by the iterator, passing in the return value from the calculation on the preceding element. The final result of running the reducer across all elements is a single value.
