Checking value in array

Checking value in array

Hey all, im kinda stuck with something so I could really use some help. I dont really know how they're called but I made this class? below:

function Artist(title, image, availability) {
this.title = title;
this.image = image;
this.availability = availability;
}

Then I filled an array with it:

var artistList = [new Artist("Aad", "Artists/Aad.png", "yes"), 
new Artist("Piet", "Artists/Piet.png", "no"), 
new Artist("Jan", "Artists/Jan.png", "yes")];

How can I check in this array which artists have a "yes" or "no" for availability?
