Let's Build a Form Around It
summary
Shows how Angular Reactive Forms power real apps by walking through concrete code: FormControl, FormGroup, FormArray and FormBuilder; built demos include a Twitter‑like input with live count and disabled submit, a password/confirm custom group validator that returns a named error, and an address check using a custom async validator against the Zippopotamus API. Demonstrates observables for valueChanges, touch/dirty/valid states, composition of nested form groups, and links to StackBlitz demos and source so the examples can be reused.
