Write a program that will take a year and report if it is a leap year.
The tricky thing here is that a leap year in the Gregorian calendar occurs:
on every year that is evenly divisible by 4
except every year that is evenly divisible by 100
unless the year is also evenly divisible by 400
For example, 1997 is not a leap year, but 1996 is. 1900 is not a leap year, but 2000 is.
If your language provides a method in the standard library that does this look-up, pretend it doesn't exist and implement it yourself.
For a delightful, four minute explanation of the whole leap year phenomenon, go watch this youtube video.
Go through the setup instructions for JavaScript to install the necessary dependencies:

Execute the tests with:
$ jasmine-node .In many test suites all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
changing xit to it.
