RxJS operators allow the following types of operations on Observables:
Transformation: Modify emitted values (e.g., map, scan).
Filtering: Emit values based on conditions (e.g., filter, take, skip).
Combination: Combine multiple Observables (e.g., merge, concat, combineLatest).
Error Handling: Handle errors gracefully (e.g., catchError, retry).
Utility: Perform side effects or utility tasks (e.g., tap, delay, toArray).
Conditional: Emit values based on conditions or other Observables (e.g., takeUntil, skipUntil).
Multicasting: Share Observable execution among multiple subscribers (e.g., share, shareReplay).
