+Answer
+a)In this program there are 5 variable declarations:
+  -const movieLength = 8784; at line 1.
+  -const remainingSeconds = movieLength % 60; at line 3.
+  -const totalMinutes = (movieLength - remainingSeconds) / 60; at line 4.
+  -const remainingMinutes = totalMinutes % 60; at line 6.
+  -const totalHours = (totalMinutes - remainingMinutes) / 60; at line 7.
+
+b) There are only 1 function call in this program.
+  - console.log(result); at line 10
+
+c)At the line 3 we can see the the expression movieLength % 60, 
+what is represent is the reminder value after the division movieLength(in second) value by 60%; 
+this is to remind how much left over second left in the movie.
+
+d)In line 4, the the expression that is assigned to totalMinutes 
+represent the value after the math operation if movieLength value and remainingSeconds then divine by 60;
+
+e)For the variable result it represent the combine total time length of the movie in hour/minutes/second template, for better name for this variable
+I would to rename it to totalMovieLength.
+
+f) After the experimenting with different values of movieLength. As Long as the value in movieLength is a positive integer of second. It will 
+correctly produce the correct value in hours/minutes/second format. However for to the other value such as float number, string, negative integer
+and non numeric value. They might still print out in the format hours/minutes/second but some type will break code such as if string not a number or coma in a string
+number, negative value that don't reflect what this code try to do or decimal number that give incorrect result.
