array and .push? waht does it do? : <p>What does this code mean? I know that we are declaring var points as an array and we're using a loop but im not too experienced to fully understand. can someone elaborate?</p>

<pre><code>  var points = [];
    for (var i = 0; i &lt; x; i++) {
      points.push( random() );
    }
    return points;
  };
</code></pre>
