<p>De <code><strong>entries()</strong></code> funtie geeft een nieuw <code><strong>Array Iterator</strong></code> object dat de key/value paren bevat voor elk onderdeel van de array.</p>

<pre class="brush:js">var a = ['a', 'b', 'c'];
var iterator = a.entries();

console.log(iterator.next().value); // [0, 'a']
console.log(iterator.next().value); // [1, 'b']
console.log(iterator.next().value); // [2, 'c']
</pre>
