How is this way of doing called? ```ts interface UserData { [key: string]: any; } class UserDataService { private userData: BehaviorSubject<UserData> = new BehaviorSubject({}); private userData$: Observable<UserData> = this.userData.asObservable(); public setUserData(userData: UserData) { this.userData.next(userData); } public getUserData(): Observable<UserData> { return this.userData$; } public getUserDataByKey(key: string) { return this.userData$.pipe(map((userData) => userData[key])); } } ```
