switchMap

• switchMap<T, S>(f: function): Transform<T, S>

• Converts each emitted item to an observable, producing values only from the most recent observable in the sequence.

  Type parameters

  • T

    Type of items emitted by the inner observables.

  • S

    Type of items emitted by the source observables.

  Parameters

  • f: function

    • • (v: T): Observable<S>

      • Parameters

        • v: T

        Returns Observable<S>

  Returns Transform<T, S>

  Transform that emits items from the most recent observable created by projecting values from the outer observable.
