 // b) How many function calls are there?
+// 1 functions, which is Console.log
 
 // c) Using documentation, explain what the expression movieLength % 60 represents
+// It represents the remainder expression. This means that the remainder operator returns the remainder left over when one operand is divided by a second operand.

 // e) What do you think the variable result represents? Can you think of a better name for this variable?
+// It creates a formated string. for example: 2:30:23. That is the movie duration formated in Hours:Minutes:Seconds.
