 // To begin, we can start with
 // 1. const penceString = "399p": initialises a string variable with the value "399p"
+// 3. we are declaring a variable and assigning it the variable penceString which holds the value "399p" but without the p - the method .subString is used
+// here to remove the p.
+// 8. we are declaring a variable and assigning it the variable penceStringWithoutTrailingP which holds the value "399
+// we are then using the .padStart method, however the method will not make any change because we have passed in the argument 3 which i
+// is the total length the string should be after padding - our string is already 3 lengths long.
+// 10. we are using a substring to slice our string from the first index to paddedPenceNumberString.length - 2, paddedPenceNumberString.length
+// will give us the number 3, so paddedPenceNumberString.length - 2 also means 3 - 2 which gives us 1, so from index 0 which is 3 to index 1 which is exclusive.
+// 15. we are declaring a variable pence and assigning it the variable paddedPenceNumberString which holds the result of a couple
+// method chains, firstly a .substring method with the argument "paddedPenceNumberString.length - 2" which also means 3 - 2, so it will
+// slice from index 1 to the end as we have not given a second argument, then we follow with a padEnd, this time we are adding
+// characters to the end of the string - we want a total of two characters
+//19. we use a string template to console log
