Reactive Forms

Short summary

Angular's reactive forms move validation logic into the component class using FormGroup and FormControl, eliminating template-based state. Built-in validators (required, email, minLength) and custom async validators automatically debounce API calls when checking server state. Subscribe to form.valueChanges with takeUntilDestroyed for memory-leak-free reactive updates.

• •FormGroup/FormControl centralizes form logic and validation in the component class
• •Async validators debounce API calls automatically via timer and switchMap without extra operators
• •takeUntilDestroyed automatically unsubscribes when the component is destroyed
