I updated the README with an external link outlining the nested rules for leap years. The present problem statement, borrowed from Chris Pine, does not clearly state these rules, which is indeed confusing. To scaffold the learner's journey, it would be useful to add a reference that walks them through the leap year rules with examples. It difficult to stick to the practice exercise if the learner has to shoot in the dark without knowing the exact rules of the game.

Exercise 06 - leapYears
Create a function that determines whether or not a given year is a leap year. Leap years are determined by the following rules:
Leap years are years divisible by four (like 1984 and 2004). However, years divisible by 100 are not leap years (such as 1800 and 1900) unless they are divisible by 400 (like 1600 and 2000, which were in fact leap years). (Yes, it's all pretty confusing)
-- Learn to Program by Chris Pine
leapYears(2000) // is a leap year: returns true
leapYears(1985) // is not a leap year: returns false
Still confused? Refer to this breakdown with examples.
Hints
- use an
ifstatement and&&to make sure all the conditions are met properly
