Array of object deep comparison with lodash
<p>I've 2 array of objects that I'd deeply compare with <code>lodash</code></p>

<p>However, I've a prob with it:</p>

<pre><code>&gt; var x = [{a:1, b:2}, {c:3, d:4}];
&gt; var y = [{b:2, a:1}, {d:4, c:3}];
&gt; _.difference(x,y, _.isEqual);
[ { a: 1, b: 2 }, { c: 3, d: 4 } ]
</code></pre>

<p>How should I compare to see that both are equal?</p>
