Issue with Artists.vue

[thott-0816]

When I try adding artists, if I don't reload the page, i can add only the first artist, and it doesn't work with next ones. I'm pretty sure the error is in the 79th line of Artists.vue, it should be:
this.newArtist = []
instead of
this.newArtist = ""
I'm learning about Vue.js and Rails api for my student projects, thank you for your build.
