Playlist!

• Create a constructor function called Artist. The Artist constructor function should have 2 properties:

  • a name property, which can be accepted as an argument of the constructor function and set on the object
  • and a songs property that defaults to an empty array

• Create a constructor function called Song. The Song constructor function should have 3 properties:

  • a title property, which can be accepted as an argument of the constructor function and set on the object
    • the title should be a string containing the title of a song
  • an artist property, which can be accepted as an argument of the constructor function and set on the object
    • the artist should be an instance of an Artist object
  • a playCount property that defaults to 0 (NOTE: playCount is not passed in as a parameter on the constructor function)

• Inside the Song constructor function, find the current song's artist property, and push the current song object into the artist's songs array property. This way, the song has a reference to the artist, and the artist has an array that contains all of their songs.

  • Think about how to refer to the current Song. What keyword does an instance use to refer to itself?

BONUS:

• Write a play() function for a Song that increments playCount.
