In this chapter, you learned about form validation with Angular Reactive Forms.
In doing so, you have used the ReactiveFormsModule, whose FormBuilder allows you to create a logical form structure and, with the help of validators, check their contents for valid entries. A bunch of built-in validators are available out of the box to support you.
You also learned how to prepare validation messages and link all this to the UI.
Finally, you will be able to create well designed forms, giving the user a good UX and your server always valid data.

Any remarks or questions?
