Unnecessary Return

[cyouh95]

Alternatively, you could simplify this:

playlistHero/src/components/App/App.js

Lines 28 to 34 in d05abe6

	addTrack(track){
	if (this.state.playlistTracks.find(savedTrack => savedTrack.id === track.id)) {
	return;
	} else {
	this.setState({ playlistTracks: [...this.state.playlistTracks, track] });
	}
	}

to:

addTrack(track){
    if (!this.state.playlistTracks.find(savedTrack => savedTrack.id === track.id)) {
      this.setState({ playlistTracks: [...this.state.playlistTracks, track] });
    }
  }

(with the use of the ! operator in the condition)
