Creates an array of elements, sorted in ascending order by the results of running each element in the `collection` through the `callback`. This method performs a stable sort, that is, it will preserve the original sort order of equal elements. The `callback` is bound to `thisArg` and invoked with three arguments; *(value, index|key, collection)*.
