Rearrange index of array to match other array

I have two arrays containing the same elements but in different order, like this:

var arr1 = [{name: 'Bob', age: 24}, {name: 'Mary',age: 45}, {random: props}]; 
var arr2 = [{name: 'Mary', age:45 }, {name: 'Bob',24}, {other: randomProps}];

In this case of course a simple reverse() would do the trick but it might be an array with 10 objects in a random order.

Since both arrays always contains some common properties (name) I should be able to rearrange one array to match the other based on name.

Any tips on how to go about this?

Maybe something like this then? But this assumes that each object in the array has the name property.

var arr1 = [{name: 'Bob', age: 24}, {name: 'Mary',age: 45}, {random: props}]; 
var arr2 = [{name: 'Mary', age:45 }, {name: 'Bob',24}, {other: randomProps}];

function sortArray(arr) {
 arr.sort(function(a, b) {
   return a.name > b.name;
 }); 
}

sortArray(arr1);
sortArray(arr2);

I think you can scan the arranged array and search elements in the second array and put them in a new array. 

new_array;
foreach(element in array_ordered)
{
    temp = search(element[name], array_unordered);
    if(temp != null)
        new_array.add(temp);
}
