In angular there are two ways to create forms in angular
1.Template driven forms
2.Reactive forms reactive forms are also called model driven forms

Reactive forms on the other hand allow us to build the form completely in code this is more flexible and has many benefits over template forms for example it’s easy to add form input elements dynamically and add just validation at runtime based on the decisions made in code it’s also easy to you know test as most of the logic and validation is in a component class the only downside of reactive forms is that they require more code than template forms.
