sync is a function that Backbone uses to handle all sending or receiving of data to/from a remote server. The default implementation uses jQuery (or Zepto) to perform AJAX operations when data is synced. However, this method can be overriden to apply different syncing behavior, such as: - Using setTimeout to batch multiple updates into a single request - Sending model data as XML instead of JSON - Using WebSockets instead of Ajax
