Forms in Angular: interview exercises

Forms in Angular: 5 test-checked interview exercises (A single FormControl, FormGroup with validators), each beside a worked example, with tests as you go. Free.

1. A single FormControl
2. FormGroup with validators
3. Custom validators
4. A growing list with FormArray
5. Template-driven with ngModel

Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
