2703. Return Length of Arguments Passed

Problem

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

Example 1:

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

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

Example 2:

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

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

Constraints:

• argsArr is a valid JSON array
• 0 <= argsArr.length <= 100

Solution (Javascript)

/**
 * @return {number}
 */
var argumentsLength = function (...args) {
  return args.length;
};

/**
 * argumentsLength(1, 2, 3); // 3
 */

Explain:

nope.

Complexity:

• Time complexity : O(n).
• Space complexity : O(n).
