Write a function called sameWeekday that takes in two dates and check if both dates have the same weekday.

For example if both dates are on a Monday the function should return true.

These asserts will test your function:

assert.equal(sameWeekday('2016-11-19', '2016-11-26'), true); assert.equal(sameWeekday('2016-11-19', '2016-11-28'), false);
