Problem

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.

Constraints:

args is a valid JSON array 0 <= args.length <= 100

Pre analysis

Will make use of destructured args to get length of arguments passed. It could laos be done via the arguments object.

Another solution

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