Create a JavaScript program that uses a loop, conditional statements, and a function to complete the following:

Using a loop, ask the user to enter the item name, price, and quantity for $3$ items.

Using a function, calculate the following:

Calculate the cost of each item and display the cost on the screen. $($price x quantity$)$

Calculate the total cost of the three items and display the total cost on the screen.

Add a shipping charge at the end of the order based on the following conditions:

If the total cost is greater than or equal to $$500,$ the shipping charge is $$30.$

If the total cost is between $$200$ and $499,$ the shipping charge is $$15.$

Otherwise, the shipping charge is $$10.$

Display the shipping charge.

Calculate the grand total of the order which includes the total cost of the three items with the shipping charge and display it on the screen.

All the numbers should display with $2$ decimal places.
