The Friends app uses the Everlive dialect of the Kendo UI Data Source
for loading the Activities. Thus said, the sync()
method is provided by the data source. Note that the data source has also a sync
event which is also used in the snippet.
As for the users of your app you can declare a data source with 'contentType' property set to 'Users' or retrieve the users directly with the JS SDK
of Backend Services.
Depending on the scenario of your app and the operations with users, you may also use the Kendo Observable Object
and use it as an update model of a current user. For multiple users you can use the Kendo Observable Array.
Let me know if further questions arise.
