Side effects with effect() in Angular
Angular interview exercise on Signals, 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 SearchBoxComponent: keep what is typed in the `query` signal, and add an effect that logs "search: <query>" with console.log every time the query changes, except when it is empty. 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.
