The concept of data binding makes it possible for any internet user to edit elements of a Web page using a web browser. No complicated scripting or programming is needed because it uses dynamic HTML. In web pages with interactive elements for example tutorials, games, calculators, forms, etc., data binding is used. Data binding is convenient when pages have a lot of data because of the incremental display of a website page. The two-way binding is used by Angular. The corresponding model state updates whenever changes are made to the user interface. The UI state is updated whenever the model state does. The framework can then use the controller to link the DOM to the Model data. As every DOM change must be tracked, this approach has an impact on performance.
