Build a Leap Year Calculator
A leap year is a year that is divisible by `4`, except for years that are divisible by `100` and not divisible by `400`. For example, `2000` is a leap year, but `1900` is not. Also, a leap year has an extra day in February, which is the 29th day of the month.
**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab.
**User Stories:**
1. Define a function called `isLeapYear` that takes a number as an argument.
2. Outside the function, declare a variable `year` that stores the value of the year you want to check.
3. Inside the function, use an `if/ else` statement or a ternary operator to check if the year is a leap year.
4. To check if the year is a leap year, fulfill the following conditions:
- If the year is divisible by `4`, then it is a leap year.
- Unless the year is also divisible by `100`, then it is not a leap year.
- Unless the year is also divisible by `400`, then it is a leap year.
5. If the year is a leap year, return `[year] is a leap year.`. Otherwise, return `[year] is not a leap year.`. You will replace `[year]` with the parameter defined in the `isLeapYear` function.
6. You should call the `isLeapYear` function with `year` as the argument and assign the result to a variable named `result`.
7. You should output the `result` variable to the console using `console.log()`.
