I have 2 arrays of objects. Now that object has Id property. Now if I have 3 array of just Ids, what is the better and faster way of finding objects from array1 and move them to array2.

Thanks a lot for answering..

Sample 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?

}
