title: Find multiple object values in array
body: <p>This is my object:</p>
  
  <pre><code>function Plane (x,z) {  
      this.x = x;
      this.z = z;
  }
  
  var plane = new Plane(0,50000);
  </code></pre>
  
  <p>I have an array with these objects:</p>
  
  <pre><code>planesArray.push(plane);
  </code></pre>
  
  <p>I have a point object:</p>
  
  <pre><code>function Point (x,z) {  
      this.x = x;
      this.z = z;
  }
  
  var point = new Point(0,-50000);
  </code></pre>
  
  <p>I need to check if in <code>planesArray</code> exist an object with the specific point, so to check if the values x and y of the point are equal to any of the planes in the array and, if NOT, to perform an action.</p>
  
  <p>I am still a novice, I apologize if this question sounds dumb.</p>
