DATA-BINDING in Angular 2

The most notable improvement to data-binding in Angular 2 is that the graph of change detectors in Angular 1 is transformed to a tree which reduces the complexity of determining when a change should be applied, thus resulting in better performance. Combined with Observable or Immutable objects you can even further optimize the change detection strategy

The Angular team also implemented two-way data-binding using the well known ng-model directive that can be used in Angular 2 forms.
