What is the difference between Template-driven and Reactive forms?

The main difference is where the form's state is managed and how you work with it.

Template-driven forms:

• Managed through HTML markup and directives (ngModel, ngForm).
• Angular creates the form structure under the hood.
• Less TypeScript code, but harder to scale.
• Suited to simple cases (registration, feedback forms).

Reactive forms:

• Fully controlled from TypeScript (FormGroup, FormControl, FormBuilder).
• Give precise control over every field and validator.
• Easier to test, change dynamically, and track changes.
• Used in complex, dynamic forms (settings, filters, admin panels).

In two words: template-driven is declarative and simple, reactive is programmatic and precise.
