Then, create another variable named idealSleepHours, set equal to the getIdealSleepHours() function call. Inside of its block, create a variable named actualSleepHours set equal to the getActualSleepHours() function call. Now that you can get the actual sleep hours and the ideal sleep hours, it’s time to calculate sleep debt.Ĭreate a function named calculateSleepDebt with no parameters. log ( getActualSleepHours ( ) ) Step 8 - Calculate Sleep Debt. should print the sum of all sleep hours in the week // if idealHours is 8, should print 56 console. You can remove the tests when you know your functions works. Test your two new functions by calling them and printing the results to the console. You’ll want to multiply by 7 to get the total hours you prefer per week. Then return the idealHours multiplied by 7. Inside the function, declare a variable named idealHours and set its value to your ideal hours per night. To get the ideal sleep hours that you prefer, create a function named getIdealSleepHours with no parameters.

Step 6 - Create/Implement getIdealSleepHours Add the results together and return the sum. Inside the getActualSleepHours() function, call the getSleepHours() function for each day of the week. To get the total sleep hours that you actually slept, create a new function named getActualSleepHours that takes no parameters.

Get the ideal sleep hours that you prefer.

Get the total sleep hours that you actually slept.

Now that you’ve written a function to get the sleep hours for each night, we need to do three things: log ( getSleepHours ( 'tuesday' ) ) Step 4 - Calculate Sleep Debt

should print the # hours assigned to tuesday console. Use an if/else or switch statement to implement this. The function should accept a day as an argument and return the number of hours you slept that night.įor instance, if you got 8 hours of sleep on Monday night, calling getSleepHours('monday') should return 8. Instead of writing seven different functions (one for each day of the week), let’s write one function with a parameter for the day.Ĭreate a function named getSleepHours with a single parameter named day. You can create a function that returns any given night’s number of hours of rest. The first problem to solve is determining how many hours of sleep you got each night of the week. Step 1 - Create function getSleepHours(day) The program will determine the actual and ideal hours of sleep for each night of the last week.įinally, it will calculate, in hours, how far you are from your weekly sleep goal. In this project we’ll calculate if you’re getting enough sleep each week using a sleep debt calculator.
