[JS Practice] Christmas day

Title :

Christmas day

Description:

Sometimes it’s useful to know on which day of week the holly holiday will occur.
But just don’t limit ourselves to this year and write a function which consumes a Christmas date and outputs a name of weekday.

Example

findOutChristmasWeekday('2013 12 25') // returns 'Wednesday'

Only valid Christmas dates will be passed to the function.

Date parameter could be a string or a Date object. If it’s a string here are possible date parameter formats:

'2013 12 25'
'12 25 2013'
'25 December 2013'

Note: calendar used in the kata is Gregorian.

[JS Practice] Boiled Eggs

Title :

Multiplication table

Description:

You are the greatest chef on earth. No one boils eggs like you! Your restaurant is always full of guests, who love your boiled eggs. But when there is a greater order of boiled eggs, you need some time, because you have only one pot for your job. How much time do you need?

Your Task

Implement a function, which takes a non-negative integer, representing the number of eggs to boil. It must return the time in minutes (integer), which it takes to have all the eggs boiled.

Rules

• you can put at most 8 eggs into the pot at once
• it takes 5 minutes to boil an egg
• we assume, that the water is boiling all the time (no time to heat up)
• for simplicity we also don’t consider the time it takes to put eggs into the pot or get them out of it

Example

cookingTime(0); // must return 0
cookingTime(5); // must return 5
cookingTime(10); // must return 10
cookingTime(16); // must return 10
