In Listing 3.7, it doesn't seem as though the following two functions are used anywhere:

  • photoArray

  • getPhotoUrl

  • I find no reference to them, but my code still seems to work completely.

    On a different note, thank you for doing an excellent job on sprinkling new 0.18 features in and explaining them; really helps as I struggle to acquire the 0.18 syntax changes.

    Thank you for the kind words! smilie

    If you take a look at the `SelectByIndex` branch of the `update` function in Listing 3.7, it's calling `getPhotoUrl`.

    `photoArray` is a bit trickier - it's used in `randomPhotoPicker`, which in turn is used in the `SurpriseMe` branch of `update`.

    Hope that helps!

    perhaps putting a note next to each name at the end pointing out where it's used would help
