title: I m confused with Object.entries()[i]
body: <p>I have checked this page : <a href="https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Objets_globaux/Object/entries" rel="noreferrer">mozilla documentation</a></p>
  
  <p>I dont understand why the index 0 with :</p>
  
  <pre><code>const object3 = { 100: 'a', 2: 'b', 7: 'c' };
  console.log(Object.entries(object3)[0]);
  
  // expected output: Array ["100", "a"] &lt;== i thought of this
  </code></pre>
  
  <p>instead the documentation says you get :</p>
  
  <pre><code>// expected output: Array ["2", "b"]
  </code></pre>
  
  <p>Someone can explain it why ?</p>
