Shouldn't the courses question actually be this.courses = [courses] in the code?

Since we are using the .push() array method on it, doesn't this.courses = courses need to be this.courses = [courses] in order for the code to work?

Because of the way it is used in all the potential answers, it is reasonable to assume that "courses" is already an array. This is also implied by the plural name, which is a common convention used for naming arrays.
