1213// For the piece of code above, read the code and then answer the following questions
1314
1415// a) How many variable declarations are there in this program?
1516
17+ // There are 6 variable declarations
18+
1619// b) How many function calls are there?
1720
21+ // There is 1 function call
22+
1823// c) Using documentation, explain what the expression movieLength % 60 represents
1924// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators
2025
26+ // % is a remainder operator.
27+ // movieLength % 60 represents the remainder when 8784/60 is calculated, which is 24 seconds
28+
2129// d) Interpret line 4, what does the expression assigned to totalMinutes mean?
2230
31+ // The expression is calculating the total number of minutes in the movie length
32+ // It does this by subtracting the remaining seconds from the total movie length, and then dividing it by 60
33+
2334// e) What do you think the variable result represents? Can you think of a better name for this variable?
2435
36+ // The result represents the movie length in hours:minutes:seconds
37+ // A better name could be hoursMinutesSeconds or movieLengthFormatted
38+
2539// f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
40+
41+ // The code will only work for positive integers
42+ // if the value is 0 or negative, the code will not make sense
43+ // if the value is a decimal, the code will give float results
44+ // if the value is not a number, the code will give an error
