Find and move an object in javascript array by id of an objects
<p>I have 2 arrays of objects. Each object has an Id property. Now, if I have a 3rd array of just Ids, what is the better and faster way of finding objects from array1 based on those Ids and moving them to array2.</p>

<p>Thanks a lot for answering..</p>

<p>Sample code:</p>

<pre><code>Person = function(id, fn, ln) {
  this.id = id,
  this.firstName = fn,
  this.lastName = ln
}

array1 = new Array();
// add 500 new Person objects to this array

array2 = new Array();
// add some other new Person objects to this array

function moveArrayItems(ids) {
  // ids is an array of ids e.g. [1,2,3,4,5,6,...]
  // Now I want to find all the person objects from array1 whose ids 
  // match with the ids array passed into this method. Then move them to array2.
  // What is the best way to achive this?
}
</code></pre>
