Can we do this.nowPlaying = (this.nowPlaying + 1 ) % this.songs.length ; to avoid if case ?

Can we do this.nowPlaying = (this.nowPlaying + 1 ) % this.songs.length ; to set the nowPlaying to zero if it exceeds the songs the length .

Hi sheshasai,

You'll still need the "if" statement to make it work. You even said it yourself in your question: "Can we do this.nowPlaying = (this.nowPlaying + 1 ) % this.songs.length ; to set the nowPlaying to zero if"

So you could use your formula, but you still need the "if" statement.

Keep Coding! :)
