+// 1. const penceString = "399p": initialises a string variable with the value "399p"
+// 2. const penceStringWithoutTrailingP = penceString.substring(0, penceString.length-1): this 
+// variable creates a new string that cuts the penceSting to 399,so it basically creates a new
+// string from index 0, and removes the last index
+// 3. const paddedPenceNumberString = penceStringWithoutTrailingP.padStart(3, "0"); this variable sets 
+// the penceStringWithoutTrailingP string length to 3, and if the length is shorter than 3 it adds 
+// "0" in front. 
+// 4. const pounds = paddedPenceNumberString.substring(0,paddedPenceNumberString.length - 2)
+// this variable uses the subString function to further slice the paddedPenceNumberString
+// string on from the first index and remove the last 2 parts of in. In this case the string goes 
+// from '399' to just '3' 
+
+// 5.const pence = paddedPenceNumberString.substring(paddedPenceNumberString.length - 2).padEnd(2, "0");
+// this variable creates a new string from the paddedPenceNumberString variable using the subString 
+// function. This time it creates a new string from the last 2 indexes. Furthermore it sets the target 
+// length for this new variable to 2 and if is is less than 2 it sets a condition to add
+// a "0" in front
+
+
+//6. console.log(`£${pounds}.${pence}`); this is a function call that displays the final amount in 
+// pounds. It uses string interpolation to directly use the variable values pound and pence and also
+//  formats the string by adding £ before the values. So the output displayed will be £3.99
