- controllers - domain objs. - services <html> views
update UI respond to user input kernel UI
updating the UI
someView.render( aViewMessage ) updating the UI {...}
someView.render( aViewMessage ) updating the UI {...}
someView.get( ‘field_id’, callbackFn ) reading the UI
someView.bind( ‘event_id’, callbackFn ) responding to events
calatrava is ‘HTML irst’
<html> <html> <html> HTML irst
HTML irst Get broad plat orm coverage quickly No glass
ceiling or UX Avoid the uncanny valley Experiment cheaply, validate, and double-down only where it matters
Testing Acceptance Tests

In Summary Strategy depends on context The Web Is The
Future ‘Hybrid’ == Mobile App Portable Body > WORA Consider Thin Client
