My code won't output anything...

Mkk · Aug 24, 2023

I'm trying to make my code output something like this:

orange: 4.1
apple: 3.84
melon: 3.06
subtotal: 11
tax: 0.88
total: 11.88

but It wont output anything

here it is:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Basic Page</title>
</head>
<body>
<script>
var cart = [] //creates an empty array for now

function createGroceryItem(name, price, quantity) {
var grocery = {"name" : name, "price" : price, "quantity": quantity, "totalPrice": function() { return price * quantity }, "printOut" : printOut};
return grocery;
}

function printOut() {
console.log(this.name + " #" + this.quantity + " : " + this.totalPrice());
}

function printReceipt(item1, item2, item3){
var subtotal =
item1.totalPrice();
item2.totalPrice(),
item3.totalPrice();
var tax = subtotal*.08;
var total = subtotal + tax;
item1.printOut();
item2.printOut();
item3.printOut();
console.log("subtotal:" + subtotal + "tax:" + tax + "ntotal:" + total);
}

cart.push(createGroceryItem("oranges", .82, 5));
cart.push(createGroceryItem("apples", .64, 6));
cart.push(createGroceryItem("melons", 1.02, 3));

printReceipt(cart[0],cart[1],cart[2]);

</script>
</body>
</html>

Well, there are some logical errors with your code, you can try below code to fix this error.

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Basic Page</title>
</head>
<body>
<script>
var cart = [];

function createGroceryItem(name, price, quantity) {
var grocery = {
"name": name,
"price": price,
"quantity": quantity,
"totalPrice": function() {
return price * quantity;
},
"printOut": printOut
};
return grocery;
}

function printOut() {
console.log(this.name + ": " + this.totalPrice().toFixed(2));
}

function printReceipt(item1, item2, item3) {
var subtotal = item1.totalPrice() + item2.totalPrice() + item3.totalPrice();
var tax = subtotal * 0.08;
var total = subtotal + tax;

item1.printOut();
item2.printOut();
item3.printOut();
console.log("subtotal: " + subtotal.toFixed(2));
console.log("tax: " + tax.toFixed(2));
console.log("total: " + total.toFixed(2));
}

cart.push(createGroceryItem("orange", 0.82, 5));
cart.push(createGroceryItem("apple", 0.64, 6));
cart.push(createGroceryItem("melon", 1.02, 3));

printReceipt(cart[0], cart[1], cart[2]);
</script>
</body>
</html>

Thanks

The issue is in the printReceipt function. You are trying to calculate the subtotal but due to the usage of commas instead of addition (+), only the last value (i.e., item3.totalPrice()) is being assigned to the subtotal variable. This makes your subtotal incorrect

function printReceipt(item1, item2, item3) {
var subtotal = item1.totalPrice() + item2.totalPrice() + item3.totalPrice();
var tax = subtotal * 0.08;
var total = subtotal + tax;
item1.printOut();
item2.printOut();
item3.printOut();
console.log("subtotal: " + subtotal);
console.log("tax: " + tax);
console.log("total: " + total);
}

another small correction is in the printOut function. You have mentioned # before the quantity, but the desired output doesn't contain #. Here's the corrected function:

function printOut() {
console.log(this.name + ": " + this.totalPrice().toFixed(2));
}
