We’ve made it to the end of the course. Congratulations! Before you go, I’d like you to complete one final exercise that will show you just how much you’ve learned about Reactive Forms in Angular. You'll need to generate controls with FormBuilder which include FormControls, FormGroups, and FormArrays. You'll even add in validation, both custom and built-in. After that, we’ll go through a possible solution and review all the topics that we’ve covered in this course. Now let’s head off to the exercise!
