 /* 1. const penceString = "399p": initializes a string variable with the value "399p"

+   2. const penceStringWithoutTrailingP = This stores the substring of penceString by extracting all characters except the final p. It takes the substring from index 0 up to (but not including) the last character p, so "399p" becomes "399". This removes the unit symbol so only the numeric portion remains.
+   3. const paddedPenceNumberString= This stores the value of penceStringWithoutTrailingP, padded to a total length of 3 characters by adding leading zeros where necessary. This guarantees there are always enough digits to separate pounds and pence correctly.
+   4. const pounds= Stores the substring of paddedPenceNumberString from index 0 to the last 2 index. These leading digits represent the pound portion of the amount.
+   5. const pence=  Extracts the final two digits of the padded string to represent the pence portion. padEnd(2, "0") ensures that the pence value always contains exactly two digits.
+   6. console.log(`£${pounds}.${pence}`); logs the value of pounds and pence into a formatted currency string using template literals
