Lesson 3 return true;


#1

My code works. Question is what purpose does adding a "return true;" serve below the switch argument?


var cashRegister = {
    total: 0,
//insert the add method here    
    add: function(itemCost) {
        this.total += itemCost;
    },
    
    scan: function (item) {
        switch (item) { 
        case "eggs": 
            this.add(0.98); 
            break;
        
        case "milk": 
            this.add(1.23); 
            break;
        
        //Add other 2 items here
        case "magazine":
            this.add(4.99);
            break;
        
        case "chocolate":
            this.add(0.45);
            break;
        }
        return true; \\ What is this?
    }
};

//Scan 2 eggs and 3 magazines
cashRegister.scan("eggs");
cashRegister.scan("eggs");
cashRegister.scan("magazine");
cashRegister.scan("magazine");
cashRegister.scan("magazine");

//Show the total bill
console.log('Your bill is '+cashRegister.total);

return true is to make sure that after the switch/case statements have been evaluated if an item is part of one of the case's it should be added. (from my understanding of control flow of course) correct me if I am wrong.
