Rxjs

RxJS operatorlari odatda 5 ta asosiy guruhga bo‘linadi:

1. Creation operators — Observable yaratadi
   of(), from(), fromEvent(), interval(), timer()
2. Transformation operators — kelayotgan datani o‘zgartiradi
   map(), switchMap(), mergeMap(), concatMap(), exhaustMap()
3. Filtering operators — kerakli qiymatlarni ajratib oladi
   filter(), take(), debounceTime(), distinctUntilChanged(), first()
4. Combination operators — bir nechta Observable’ni birlashtiradi
   combineLatest(), forkJoin(), merge(), concat(), zip()
5. Error Handling / Utility operators — xatolarni boshqarish yoki Observable xatti-harakatini nazorat qiladi
   catchError(), retry(), tap(), finalize()

combineLatest — Bittasi o’zgarsa, eng so‘nggi qiymatlar bilan yana natija chiqaradi.

forkJoin() — Barcha Observable’lar tugashini kutadi va oxirgi qiymatlarni bir marta chiqaradi.

merge() — Bir nechta Observable’ni bitta oqimga qo‘shadi va kim qiymat chiqarsa, o‘sha zahoti chiqaradi.

zip() — U Observable’lardan mos juftlikdagi qiymatlarni kutadi.
