Destructuring array get second value? : <p>How to get array using destructing? </p>

<pre><code>const num = [1,2,3,4,5];
const [ first ] = num; //1
</code></pre>

<p><code>console.log(first)</code> I'm able to get 1, but when I try to do <code>const [ null, second ] = num</code> it has expected token error. How to get 2nd item of num array?</p>
