Returns a sorted array of the values in this collection.

The comparator must be a function that accepts two values and returns a number.

• less than zero if the left is less than the right
• more than zero if the left is more than the right
• equal to zero if the left is either incomparable or equivalent to the right

A comparator for numbers should subtract the right from the left and expresses both the direction and magnitude of the difference. If the magnitude of the difference is not meaningful, a comparator should return only Infinity, -Infinity, or 0, to increase the usefulness of the comparator.

The default comparator is Object.compare.
