signal and computed in Angular
Angular interview exercise on Signals, difficulty 1 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Write the class for CounterComponent: a `count` signal starting at 0, a `double` computed from it, increment() adding one and reset() going back to 0. The template is written for you.
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.
