 // To begin, we can start with
 // 1. const penceString = "399p": initialises a string variable with the value "399p"
+// 2. const penceStringWithoutTrailingP = "399p".substring( 0,  penceString.length - 1): Here we use the subString method which will slide the string of 
+// penceString starting at index 0 and ending at index 2 (3 - 1). The result should be "399"
+// 3. const paddedPenceNumberString = penceStringWithoutTrailingP.padStart(3, "0"): Here we want to make sure that the penceStringWithoutTrailingP variable has at least 3 characters, if that is not the case, we will add "0" infront of the character till it reaches the length required.
+// Here, paddedPenceNumberString = "399" . Then pounds =  "3"
+// 4. const pence = paddedPenceNumberString.substring(paddedPenceNumberString.length - 2).padEnd(2, "0") : The substring(paddedPenceNumberString.length - 2) will return 99  and the padEnd(2,"0") will make sure that there are at least two characters here.
