switchMap How switchMap Works: It takes an observable as input. For each emission from the input observable, it applies a function that returns a new observable. It subscribes to the new observable and unsubscribes from any previous one. It emits the values from the latest observable. Benefits of switchMap : Cancels previous requests when a new one is made, preventing race conditions. Ideal for scenarios where only the latest result is needed. Simplifies handling of multiple asynchronous operations.
