Dr Strange

Instructions

You have been given the mission to create a new sense of time! Normally a week has 7 days right? Well, that is about to change!

Instead of a normal week having only 7 days, it will have 14 days. Let me explain, this new week will have 14 days, from Monday to Sunday then secondMonday to secondSunday. Your purpose is to create a new function addWeek, that takes as parameter a Date and that will return what week day the given date is, according to your new week format. Week number should be count from 0001-01-01.

new week format:

Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
secondMonday
secondTuesday
secondWednesday
secondThursday
secondFriday
secondSaturday
secondSunday

Now imagine you have a doctor appointment and you have to wait some hours, but you do not want to wait, so you decided that you need to create a function timeTravel that allows you to change the time according to your needs. This function will give you the power to go backwards or forwards in time.

So, you will have a function that takes an object with the following {date, hour, minute, second}. This object will be responsible for changing the hour, minute and second of the given date.

Example

addWeek(new Date('0001-01-01')) // Output: Monday
addWeek(new Date('0001-01-02')) // Output: Tuesday
addWeek(new Date('0001-01-07')) // Output: Sunday
addWeek(new Date('0001-01-08')) // Output: secondMonday
addWeek(new Date('0001-01-09')) // Output: secondTuesday

// timeTravel({ date, hour, minute, second })

timeTravel({
  date: new Date('2020-05-29 23:25:22'),
  hour: 21,
  minute: 22,
  second: 22,
}).toString()

// Output: Fri May 29 2020 21:22:22 GMT+0100 (Western European Summer Time)
