Javascript sort callback

Question

I need to sort a big list of Javascript items and I'm using the sort function like this:

var sorted_list = non_sorted.sort(function(a,b){
// Sort stuff here
});

What I'd like to do is to call a function when the sort function is done.

Is it possible to add a callback function to sort or to trigger an event when when sort is over?

Solution

You are overcomplicating it. The sort method isn't asynchronous, so you don't need a callback or an event. Just put your code after the code that calls sort:

var sorted_list = non_sorted.sort(function(a,b){
  // comparer
});
// The code just continues here after the sort

You can just add the function to call after you've sorted the list.

.sort() is synchronous.

As suggested, you can do arr.sort(comparefn).arrMethod() or someFn(arr.sort(comparefn)) since sort returns the sorted object.

@epascarello just for the hell of it :P And I figured I'd make it a prototype just to show how this can be done.

Consider replacing resultFunction(result) with resultFunction.apply(result, arguments) to allow arguments to be passed to resultFunction. But extending built–ins isn't a good idea.
