If else in react.js(basic)

I am building a simple single page app on react.js for the first time using spotifys api keys. Ive managed to get the song info on the page when a user is playing a song. How can I add an else statement to this so that I have something like "No Playback deteced" appear when nothing is playing?

{ (() => {
          if (this.state.nowPlaying.id) {

            return (
              <div>
                <div> Now Playing: { this.state.nowPlaying.name} </div>
                <div> By: { this.state.nowPlaying.artist} </div>
                <div> Id: { this.state.nowPlaying.id} </div>
                <div> Progress: { this.state.nowPlaying.progress} </div>
                <div>
                  <img src={ this.state.nowPlaying.image} style=/>
                </div>
                <AudioFeatures
                 id={this.state.nowPlaying.id}
                 ref={this.audioFeatures}
                 oAuth={this.state.oAuth}
                />
              </div>
            );
          } 
        }

        })()
      }

Thanks.
