🟠 High Order Operator Bug
Challenge #11
Let’s dive inside the wonderful word of RxJs.
This challenge is inspired by a real-life example.
Presentation of the challenge
User Story
We need a button for each Topic. When we click on it, we delete all objects with this Topic in our database (Fake DB in our case). Finally we display All [topic] have been deleted is everything was deleted successfully or Error: deletion of some [topic] failed if some deletions failed
Constraints:
We can only pass one object to our DB for deletion at the time. The DB will respond true if the data was successfully deleted and false otherwise.
What you need to do
The QA team reports a bug. The UI shows All [topic] have been deleted all the time, even if some deletions fail.
👉 Spot the bug and correct it.
