Angular provides two ways to work with forms: template-driven forms and reactive forms (also known as model-driven forms). Template-driven forms are the default way to work with forms in Angular. With template-driven forms, template directives are used to build an internal representation of the form. With reactive forms, you build your own representation of a form in the component class.

Note: Reactive forms were introduced with Angular 2.

• Using custom validators
• Changing validation dynamically
• Dynamically adding form fields
