What are the benefits of using Template-driven forms in Angular 8?

Following are the benefits of using Template-driven forms:

You should use Template-driven forms if you want to add a simple form to your application because template-driven forms use two-way data binding to update the data model in the component. By using this, you can see the changes instantly as you make changes in the template and vice versa.
Template-driven forms are easy to use in the application, but they are not as scalable as Reactive forms, so they are preferred to use in test applications for learning purposes.
Template-driven forms are mainly used if your application requires a very basic form and logic. It can easily be managed in a template.
