Live coding interviews often feature RxJS challenges. Memorizing these three operator distinctions will save your live coding score: Behavior on New Emission Best Use Case Cancels the previous inner observable. Search typeaheads (drops old pending HTTP requests). mergeMap Runs all inner observables concurrently. Deleting multiple items where order does not matter. concatMap Queues inner observables and runs them sequentially. Database saves where sequential order is critical. 🔒 Security and Route Guarding
