+<h2><a href="https://leetcode.com/problems/is-object-empty">2727. Is Object Empty</a></h2><h3>Easy</h3><hr><p>Given an object or an array, return if it is empty.</p>
+
+<ul>
+	<li>An empty object contains no key-value pairs.</li>
+	<li>An empty array contains no elements.</li>
+</ul>
+
+<p>You may assume the object or array is the output of&nbsp;<code>JSON.parse</code>.</p>
+
+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> obj = {&quot;x&quot;: 5, &quot;y&quot;: 42}
+<strong>Output:</strong> false
+<strong>Explanation:</strong> The object has 2 key-value pairs so it is not empty.
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> obj = {}
+<strong>Output:</strong> true
+<strong>Explanation:</strong> The object doesn&#39;t have any key-value pairs so it is empty.
+</pre>
+
+<p><strong class="example">Example 3:</strong></p>
+
+<pre>
+<strong>Input:</strong> obj = [null, false, 0]
+<strong>Output:</strong> false

+<ul>
+	<li><code>obj</code> is a valid JSON object or array</li>
+	<li><code>2 &lt;= JSON.stringify(obj).length &lt;= 10<sup>5</sup></code></li>
