This function can be set in scenarios where you want to optimize or customize the tracking of changes for the items in the collection.\r\nThe trackBy function takes the index and the current item as arguments and needs to return the unique identifier for this item.\r\nBy default the object references are compared, however this can be optimized if you have unique identifier value that can be used for the comparison instead of the object ref or if you have some other property values in the item object that should be tracked for changes.\r\nThis option is similar to ngForTrackBy.
