2727. Is Object Empty

Easy

---

Given an object or an array, return if it is empty.

• An empty object contains no key-value pairs.
• An empty array contains no elements.

You may assume the object or array is the output of JSON.parse.

---

Example 1:

obj = {"x": 5, "y": 42}
// Output: false

Explanation :

The object has 2 key-value pairs so it is not empty.

Example 2:

obj = {}
// Output: true

Explanation :

The object doesn't have any key-value pairs so it is empty.

Example 3:

obj = [null, false, 0]
// Output: false

Explanation :

The array has 3 elements so it is not empty.

Constraints :

• obj is a valid JSON object or array
• 2 <= JSON.stringify(obj).length <= 105
