Interpolation and property 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.
Write the template of UserBadgeComponent. Show the avatar as <img class="avatar"> with its src bound to `avatar` and its alt set to the name followed by " avatar". Show the name in <span class="name">, with the class "online" while `online` is true. Then a <span class="status"> that reads "online" or "away".
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.
