RxJS & Angular Reactive Forms @ Codemotion 2019
The document discusses reactive forms in Angular, comparing them to template-driven forms. Reactive forms are built around Observable streams, handle dynamic value changes, and offer benefits like immutability, testability, and scalability compared to template-driven forms. It provides an overview of key concepts like FormControl, FormGroup, and FormBuilder and examples of how to implement basic and nested reactive forms, add validators, update forms dynamically, and handle form submission and arrays.
