Template references and keyboard events in Angular
Angular interview exercise on Components & templates, difficulty 2 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 ShoppingListComponent. Enter in the <input> or clicking the Add button adds what was typed to `items` (trimmed; blank input is ignored) and clears the box. Each <li> holds the item in a <span> and a <button class="remove"> that removes that item.
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.
