 // To begin, we can start with
 // 1. const penceString = "399p": initialises a string variable with the value "399p"
+// 2. const penceStringWithoutTrailingP = penceString.substring(0, penceString.length - 1): creates a new string variable that contains the 
+// original string without the last character (the "p"). 
+// 3. const paddedPenceNumberString = penceStringWithoutTrailingP.padStart(3, "0"): creates a new string variable 
+// that pads the previous string with leading zeros until it is at least 3 characters long. eg. "45" becomes "045" and "7" becomes "007".
+// 4. const pounds = paddedPenceNumberString.substring(0, paddedPenceNumberString.length - 2): creates a new string variable that contains 
+// the first part of the padded string, which represents the pounds. It takes all characters except the last two. eg. "045" becomes "0" and "399" becomes "3".
+// 5. const pence = paddedPenceNumberString.substring(paddedPenceNumberString.length - 2).padEnd(2, "0"): creates a new string variable that contains the 
+// last two characters of the padded string, which represents the pence. It also pads it with trailing zeros if necessary to ensure it is 2 characters long. 
+// eg. "045" becomes "45" and "7" becomes "70".
+// 6. console.log(`£${pounds}.${pence}`): outputs the final price in pounds and pence format to the console. For example, if penceString is "399p", 
+// it will output "£3.99". If penceString is "45p", it will output "£0.45". If penceString is "7p", it will output "£0.07".
