Convenience method to get sub-indices of array in javascript
<p>Is there a convenient way to get say the first n number of indices from this array: </p>

<pre><code>var alphabet = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'];
</code></pre>

<p>and store it in another array, say <code>alphabet2 = ['a','b','c'];</code> without having to brute force with a loop? Thanks</p>
