 // Pay particular attention to the following:
 
 // a) How the index variable updates during the call to find
+// [MM] - The index variable increments by one each time the letter (str[index]) at the current index does not match the target letter (char)
 // b) What is the if statement used to check
+// [MM] - The if statement is used to check if the current letter matches the target letter (char).  If a match is found (str[index] === char) it will cause an early exit from the while loop at the current index
 // c) Why is index++ being used?
+// [MM] - The index++ increments the index variable by one each time the current letter (str[index]) does not match the target letter (char).  It only runs if a match is not found
 // d) What is the condition index < str.length used for?
+// [MM] - The condition index < str.length is used to set the upper bound of the loop (the loop will run while index number is less than str.length)
