1. Let codePoints be a List containing the arguments passed to this function.
2. Let length be the number of elements in codePoints.
3. Let elements be a new List.
4. Let nextIndex be 0.
5. Repeat while nextIndex < length
a. Let next be codePoints[nextIndex].

c. ReturnIfAbrupt(nextCP).
d. If SameValue(nextCP, ToInteger(nextCP)) is false, throw a RangeError
exception.
