Return Length of Arguments Passed
Implement argumentsLength so that it returns how many positional arguments were passed to that call. Each supplied value counts once, including null, an object, or an array; nested contents do not add more arguments. Practice approach: A rest parameter collects the call arguments into an array, whose length is the result. Do not count only truthy values, and do not use the function's declared parameter count. With a rest-array implementation, collecting n arguments costs O(n) time and space; reading the collected length is O(1). Test a call with no arguments and a call containing null.
