//INSTRUCTIONS--
/* You are given the length and width of a 4-sided polygon. The polygon can either be a rectangle or a square.
If it is a square, return its area. If it is a rectangle, return its perimeter.

area_or_perimeter(6, 10) --> 32
area_or_perimeter(3, 3) --> 9
Note: for the purposes of this kata you will assume that it is a square if its length and width are equal, otherwise it is a rectangle.
*/ 
 
//SOLUTION--
/* I refactored the original foundation for the function to take on a more concise arrow function with the ternary operator syntax. If the length
and width are the same it is a square so we return the length multiplied by the width. If they are not the same that means that are a rectangle and
we will add the lengths and the widths together to get a perimeter.
