title: Push multiple elements to array
body: <p>I'm trying to push multiple elements as one array, but getting an error:</p>
  <pre><code>&gt; a = []
  []
  &gt; a.push.apply(null, [1,2])
  TypeError: Array.prototype.push called on null or undefined
  </code></pre>
  <p>I'm trying to do similar stuff that I'd do in ruby, I was thinking that <code>apply</code> is something like <code>*</code>.</p>
  <pre><code>&gt;&gt; a = []
  =&gt; []
  &gt;&gt; a.push(*[1,2])
  =&gt; [1, 2]
  </code></pre>
