Re: Web API Design Cookbook

Robin et al,

Thanks for pushing this forward.

I have received few questions from the Tizen team about the preferred
style related to asynchronous operations. In the cookbook you outlined few
options in chapter 5.

Which would be the better style for asynchronous operations: callbacks or
DOM events?

- Some W3C APIs (Contacts, Calendar, Messaging, Geolocation, ...) pass
success/error callbacks as argument to methods.

- Some more recent W3C specs (FileAPI, FileWriter, IndexedDB) use DOM

Seems that Mozilla B2G is moving towards DOM events in their
implementation [1].

So is there any preferred way, or is it just pick what ever you feel like?

Another question is related to notifications. That is,

- Some W3C APIs (geolocation, systeminfo) use watchChanges()/clearWatch()
style with callbacks.

- Recent W3C specs ( FileAPI, FileWriter, IndexedDB, battery, sensors)
uses DOM Events.

Any preferred way here as well?
