Angular Form

Angular Form is a Web Form where user enter the data and click on submit button then data is passed to business logic (means data passed to Server API or any other logic implement).

There are two types of forms in the angular.
1) Template Driven Form
2) Model-Driven Form (Reactive Form)

Template-Driven Forms:

Template-driven forms in Angular provide a simple, declarative way of building forms. They are based on Angular’s two-way data binding and use directives in the template (such as ngModel) to define the form structure and validation directly in the HTML. This approach is ideal for smaller forms or when you don’t need the complexity and flexibility of reactive forms.

Use Case: Ideal for simple forms requiring minimal code, such as basic contact or login forms.

Reactive Forms:

A Reactive Form in Angular is a way to build forms using a model-driven approach. This means that the form and its validation logic are defined in the component class, giving you more control over the form’s structure and behavior. Reactive forms are built using a combination of objects provided by Angular, such as FormGroup, FormControl, and FormArray, to manage form fields and their states (like validity, touched, dirty, etc.).

Use Case: Ideal for complex forms with dynamic validation, custom validators, and forms that require more control over the form state.
