+""" The Smart Checkout System
+Objective: Create a python program that simulates a simple shopping cart checkout process.
+
+Instructions for Students:
+Write a code script that performs the following steps in order:
+
+Setup the Store:
+
+Create a const variable for walletBalance and set it to 5000.
+Create an array called cartItems containing three prices: [500, 1200, 350].
+Manage the Cart (Array Operations):
+
+A new item is added! Use .push() to add a price of 2000 to the cart.
+Oops, that item is too expensive. Use .pop() to remove the last item.
+Create a new array called recommendedItems with prices [100, 200].
+combine recommendedItems and cartItems into a new array called finalCart using the Spread Operator (...).
+Calculate Totals (Math & Operators):
+
+Calculate the sum of the prices in finalCart (Hint: since we don't have loops yet, access them manually like finalCart[0] + finalCart[1]...).
+Store this sum in a variable totalPrice.
+Add a 10% tax to the logic. Update totalPrice to include the tax.
+Round the totalPrice to 2 decimal places using .toFixed().
+Coupon Code Handling (String Manipulation):
+
+Create a variable couponCode with the messy value "   DisCOunT10   ".
+Clean up the code: Remove the whitespace using .trim() and convert it to uppercase.
+If the cleaned code is "DISCOUNT10", subtract 500 from the totalPrice.
+Final Decision (Conditionals):
+
+Write an if/else statement:
+If totalPrice is less than or equal to walletBalance: Console log "Purchase Successful! New Balance: [Remaining Amount]".
+Else: Console log "Insufficient Funds! You need [Missing Amount] more."
+Receipt Generation (Randomness):
+
+Generate a random Order ID between 1 and 100 using Math.random() and Math.floor().
+Console log a receipt message using Template Literals (backticks): Order [ID] confirmed. Thank you for shopping!
