2703. Return Length of Arguments Passed

Write a function argumentsLength that returns the count of arguments passed to it.

Example 1:

Input: args = [5]
Output: 1
Explanation:
argumentsLength(5); // 1

One value was passed to the function so it should return 1.

Example 2:

Input: args = [{}, null, "3"]
Output: 3
Explanation:
argumentsLength({}, null, "3"); // 3

Three values were passed to the function so it should return 3.

var argumentsLength = function(...args) {
    return args.length
};
