 // 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): This removes the letter 'p' from the end of the string,
+// leaving just the numbers part of the string. The substring method is used to extract a portion of the string,
+// starting from index 0 and ending at the second-to-last character (length - 1).
+
+// 3. const paddedPenceNumberString = penceStringWithoutTrailingP.padStart(3, "0"); This is to ensure the numbers presented after the substring is at least 3 characters long,
+// if the number is shorter the computer would add '0' or '0's in front of the number to make it 3 digits long.
+
+// 4. const pounds = paddedPenceNumberString.substring(0, paddedPenceNumberString.length - 2):
+// This extracts the pounds part of the string by taking all characters except the last two.
+
+// 5. const pence = paddedPenceNumberString.substring(paddedPenceNumberString.length - 2).padEnd(2, "0");
+// This extracts the pence part of the string by taking the last two characters and ensures that it is at least 2 characters long by adding '0' at the end
+// if necessary as this is because we need the decimal value.
+
+// 6. console.log(`£${pounds}.${pence}`): This outputs the final answer in the format of pounds and allows the user to see the final result also.
