// For the piece of code above, read the code and then answer the following questions
// a) How many variable declarations are there in this program?
//6 variable declarations
// b) How many function calls are there?
//1 function call
// c) Using documentation, explain what the expression movieLength % 60 represents
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators
//% it's the remainder operator and it tells us how many seconds are left out of a whole minute
// d) Interpret line 4, what does the expression assigned to totalMinutes mean?
//total time in minutes without the remaining seconds
// e) What do you think the variable result represents? Can you think of a better name for this variable?
//it represents the total movie time , so.... const timeInHhMmSs perhaps
// f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
//it will work with all values as long as they are numbers,
