示例1: concatMap

    concatMap((action: actions.KillKernelAction) => {
      const state = state$.value;

      const host = selectors.currentHost(state);
      if (host.type !== "jupyter") {
        // Dismiss any usage that isn't targeting a jupyter server
        return empty();
      }
      const serverConfig: ServerConfig = selectors.serverConfig(host);

      const kernel = selectors.currentKernel(state);
      if (!kernel) {
        return of(
          actions.killKernelFailed({
            error: new Error("kernel not available for killing"),
            kernelRef: action.payload.kernelRef
          })

              "websocket kernel epic can only kill websocket kernels with an id"
            ),
            kernelRef: action.payload.kernelRef
          })
        );
      }

      // TODO: If this was a kernel language change, we shouldn't be using this
      //       kill kernel epic because we need to make sure that creation happens
      //       after deletion
