I can not find the error at this moment. SyntaxError: Expected ':'


var cashRegister = {
    this.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;
    }
};

//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);

You don't need this keyword here.

var cashRegister = {
    this.total: 0,

in your code you write this.total: 0 ^^
but it's already there as total: 0, and you switched it?

this.total

doesn't really mean anything in this scenario and therefor the code doesn't work...
