sleep-tracker.js

// 1. The first problem to solve is determining how many hours of sleep you got each night of the week. You can create a function that returns any given night’s number of hours of rest. Instead of writing seven different functions (one for each day of the week), let’s write one function with a parameter for the day.
// 2.The function should accept a day as an argument and return the number of hours you slept that night. For instance, if you got 8 hours of sleep on Monday night, calling getSleepHours('monday') should return 8. Use an if / else or switch statement to implement this.
// 3. Test the function by calling it multiple times and printing the results to the console. You can remove the tests when you know you function works.
// 4. Now that you’ ve written a function to get the sleep hours for each night, we need to do three things:
// - Get the total sleep hours that you actually slept
// - Get the ideal sleep hours that you prefer
// - Calculate the sleep debt, if any.
// 5. Inside the getActualSleepHours() function, call the getSleepHours() function for each day of the week.Add the results together and return the sum using an implicit return.
// 6. To get the ideal sleep hours that you prefer, create a function named getIdealSleepHours with no parameters. You’ll want to multiply by 7 to get the total hours you prefer per week.
// 7. Test your two new functions by calling them and printing the results to the console. You can remove the tests when you know your functions works.
// 8.Now that you can get the actual sleep hours and the ideal sleep hours, it’s time to calculate sleep debt.
// 9.Now that you have actualSleepHours and idealSleepHours, you can write a few if/else statements to output the result to the console. The function should fulfill this logic:
// - If actual sleep equals ideal sleep, log to the console that the user got the perfect amount of sleep.
// - If the actual sleep is greater than the ideal sleep, log to the console that the user got more sleep than needed.
// - If the actual sleep is less than the ideal sleep, log to the console that the user should get some rest.
// 10. To make this calculator more helpful, add the hours the user is over or under their ideal sleep in each log statement in calculateSleepDebt().
// 11. On the last line of the program, start the program by calling the calculateSleepDebt() function.
// 12. For extra practice, try these:
// - getActualSleepHours() could be implemented without calling getSleepHours(). Use literal numbers and the + operator to rewrite getActualSleepHours(). It should still return the total actual hours slept in the week.
// - Some people need to sleep longer than others. Rewrite getIdealSleepHours() so that you can pass it an argument, like getIdealSleepHours(8) where 8 is the ideal hours per night. Update the call to getIdealSleepHours() in calculateSleepDebt() too.
