What’s the difference between template-driven and reactive forms in Angular, and when should I use each?

I'm trying to understand the difference between template-driven and reactive forms in Angular. Can someone explain how they differ and when I should use each approach?"

Answer 1

Aspect	Template-Driven Forms	Reactive Forms
Programming Paradigm	Declarative: The template mostly contains the form logic.	Imperative: The component defines form logic.
Data Binding	Data binding in both directions with the ngModel directive.	FormGroup and formControlName are used for explicit binding.
Complexity Handling	Ideal for basic forms and situations.	Suitable for dynamic form elements and complex forms.
Validation	Validators are applied using template directives (e.g., required, pattern).	Validators are explicitly defined in the component code.
Unit Testing	Unit testing is relatively straightforward.	Unit testing is more straightforward due to better programmatic control.
Community Preference	For small to medium-sized projects, this method is frequently chosen.	preferred for more extensive constructions with intricate form specifications.
