Reactive forms is an Angular technique for creating forms in a reactive style.
Example of forms in angular. Angular reactive forms facilitate a reactive style of programming that favors explicit management of the data flowing between a non-UI data model typically retrieved from a server and a UI-oriented form model that retains the states and values of the HTML controls on the screen. We have used Reactive Forms in our example in this article. The ng-app directive defines the AngularJS application.
