if I add a console.log to your code:
getRandomDishFromCourse(courseName){
const dishes = this._courses[courseName];
const randomIndex = (dishes[Math.floor(Math.random() * dishes.length)]);
console.log(dishes, randomIndex);
return dishes[randomIndex];
},
I see that your randomIndex variable does not contain a random index, but rather you already use the random index to get a random value.
