PROBLEMS

Description

---

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

Example

---

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.

Example 3:

Input: functions = [], x = 42
Output: 42
Explanation:
The composition of zero functions is the identity function

Constraints

---

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

Solution

---

• Runtime: 52ms
• Memory: 48.28MB

/**
 * @param {...(null|boolean|number|string|Array|Object)} args
 * @return {number}
 */
var argumentsLength = function(...args) {
    return args.length
};

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

이번 문제를 파라미터로 들어온 배열의 길이를 구하는 문제여서 정말 쉽게 문제를 풀었던거 같다.
