Tell us what’s happening:
I want to understand more about the definition of Mixin. Why is it necessary to write the obj.fly property as a function instead of just a return or console.log(“Flying, woosh!”)? It basically does the same thing that puts this property into the subtypes. Does it not make the GlideMixin function as a mixin?
Your code so far
let bird = {
name: "Donald",
numLegs: 2
};
let boat = {
name: "Warrior",
type: "race-boat"
};
// Add your code below this line
let glideMixin = function(jj) {
jj.glide = function() {
console.log ("im gliding");
}
}
glideMixin(boat);
glideMixin(bird);
console.log(bird.glide);
console.log(boat.glide);
