Find duplicate elements between two arrays
<p>i tried find element in two arrays but doesn't work. compare value x
in javascript</p>

<p><strong>values</strong> = </p>

<p>(1) height:33 id:0 width:41 <strong>x:703.2585296630859</strong> y:246.32955852224802</p>

<p><strong>valueArea</strong> = </p>

<p>(1) height:33 id:2 width:41 <strong>x:703.2585296630859</strong> y:246.32955852224802 </p>

<p>(2) height:21 id:1 width:60 <strong>x:672.8721689562212</strong> y:213.45216754521646</p>

<pre><code>for(var i=0; i&lt;values.length;i++){
    for(var j=0; j&lt;valueArea.length; j++){
        if(values[i].x != valueArea[j].x){
            valueArea.push(values[i]);                  
        }
    }
}
</code></pre>
