Event binding in Angular
Angular interview exercise on Components & templates, 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.
Finish StepperComponent: a <button class="dec"> and a <button class="inc"> around an <output> showing `value`. Clicking changes the value by one; it never goes below 0, and the dec button is disabled while the value is 0 (bind its disabled property).
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.
