* and `deletions`, each containing a list of indices in the collection that were
* inserted, updated or deleted respectively. `deletions` and `oldModifications` are
* indices into the collection before the change happened, while `insertions` and
* `newModifications` are indices into the new version of the collection. If partial sync
* is enabled, an additional key `partial_sync` is added.
* - `changes.partial_sync`: `error` indicates if an error has occurred, `old_state` is the previous
* state, and `new_state` is the current state.
* `newModifications` are indices into the new version of the collection.
* @throws {Error} If `callback` is not a function.
* @example
* wines.addListener((collection, changes) => {
* // collection === wines
* if (changes.partial_sync.new_state == Realm.Sync.SubscriptionState.Initialized) {
* console.log('Our subset is ready');
* console.log(`${changes.insertions.length} insertions`);

* console.log(`${changes.deletions.length} deletions`);
* console.log(`new size of collection: ${collection.length}`);
