Answer
Data binding connects the component class and the template.
Types include interpolation, property binding, event binding, and two-way binding.
Quick Answer
Data binding connects component data to the template. Four types: Interpolation {{value}} (display), Property binding [property]="value" (DOM property), Event binding (click)="handler()" (DOM events), Two-way binding [(ngModel)]="value" (combines property + event binding). Two-way binding is syntactic sugar: [(x)] expands to [x] + (xChange).
