JavaScript Subjective Test

Q 1. You are creating a program to calculate the total bill amount for a restaurant. Create a JavaScript program that defines a class Order to represent each order with a dish name, price, and quantity. A program that defines the Order class and uses some built-in functions to manipulate and display the data is given.
Complete the code as per the given instructions:
At Blank 1: Use the method that calculates the total bill amount for all the orders in the orders array.
At Blank 2: Analyze the code and get the Total bill value from the total order.
At Blank 3: Use the method that sorts the orders array based on the price of each order.
At Blank 4: Use the method that filters the orders array based on the condition that the price of each order should be greater than or equal to 10.
At Blank 5: Loop through the orders array and display each order's dish name, price, and quantity.
A few lines in the Sample Script are missing (Enter your code here). You need to complete the code as per the given instructions.
Sample Script: class Order { dishName; price; quantity;
constructor(dishName, price, quantity) { this.dishName = dishName; this.price = price; this.quantity = quantity; }
getTotalPrice() { return this.price * this.quantity;
} }
const orders = [ new Order("Burger", 8, 2), new Order("Pizza", 12, 1), new Order("Sandwich", 6, 3), new Order("Pasta", 10, 2), new Order("Coke", 2, 4), ];
const totalBillAmount =
((total, order) =>
,0);
console.log(Total Bill Amount: ${totalBillAmount});
const sortedOrders = orders. ((a, b) => a.price - b.price);
console.log("Sorted Orders:"); console.log(sortedOrders); const filteredOrders = orders. console.log("Filtered Orders:");
console.log(filteredOrders);
console.log("All Orders:");
(order => { console.log(${order.dishName} - ${order.price} x ${order.quantity} = ${order.getTotalPrice()}); });
