 // This program takes a string representing a price in pence
 // The program then builds up a string representing the price in pounds
 
 // You need to do a step-by-step breakdown of each line in this program
 // Try and describe the purpose / rationale behind each step
 
 // To begin, we can start with
-// 1. const penceString = "399p": initialises a string variable with the value "399p"
+// 1. const penceString = "399p": initializes a string variable with the value "399p"
+
+//2. const penceStringWithoutTrailingP = penceString.substring(
+  //   0,
+  //   penceString.length - 1
+  // );
+  //initializes a string variable with the value "399" by removing the last character "p" from penceString
+
+//3.  const paddedPenceNumberString = penceStringWithoutTrailingP.padStart(3, "0");
+  //initializes a string variable with the value penceStringWithoutTrailingP, with a minimum length of 3 characters, if it happens to be shorter it will add a "0" at the beginning of the string for every character that is short
+
+//4.  const pounds = paddedPenceNumberString.substring(
+//   0,
+//   paddedPenceNumberString.length - 2
+// ); 
+  //initializes a string variable with the value of paddedPenceNumberString except the final 2 characters, thus extracting the pounds, in this case "3"
+
+//5.   const pence = paddedPenceNumberString
+// .substring(paddedPenceNumberString.length - 2)
+// .padEnd(2, "0")
+  //it extracts the last two characters (pence) from paddedPenceNumberString and it makes sure that there's always gonna be two by adding "0" at the end
+ 
+//6.  console.log(`£${pounds}.${pence}`);
+  //it logs £3.99
