Data Binding in Angular 2
summary
Angular 2 organizes the app as a component tree and replaces Angular 1’s many interdependencies with clear rules: property bindings flow top-down and require one digest cycle to synchronize the UI after events, while event bindings flow bottom-up and simply call callbacks. Development mode enforces that children cannot mutate parent state (production skips the check). Two-way binding is explicit sugar: use a property plus an event named PropertyNameChange and read the new value from $event.
