A single FormControl in Angular
Angular interview exercise on Forms, 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.
SearchComponent has a `query` FormControl (string, nonNullable) bound to the <input>. <p class="echo"> shows "Searching for <query>" or "Type to search" when empty, and <button class="clear"> resets the control. Bind the input and write the class.
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.
