Angular Forms

Template-driven forms and Reactive forms are two approaches to handling forms in Angular.

Template-Driven Forms:
Approach:
Template-driven forms are more declarative and rely on directives in the template to create and manipulate the form controls. Form controls are bound to the template using directives like ngModel, ngForm, and others.
ngModel is a key feature, providing two-way data binding between the form controls and component properties.
Choose template-driven forms for simpler forms with less complex logic.

Reactive Forms:
Approach:
Reactive forms are more programmatic and require the explicit creation of form controls and groups in the component class.
Form controls are created using TypeScript code, providing more control and flexibility.
Choose reactive forms for complex forms with dynamic controls and advanced validation requirements.
