How should client-side datastores & persistence be handled in a single-page web application?

Global vars vs. DI/IoC: Should datastores be assigned to global variables so any part of the application can access them? Or should they be dependency injected where required?
Server persistence: Assuming a datastore's data needn't always be persisted to the server immediately, should the datastore itself handle persistence? If not, then what class should handle persistence and how should the persistence class fit into the client-side architecture overall?
Is the datastore considered the model in MVC, or is it something else since it just stores raw data?
