	  Not really sure which of these is the 'better' alternative
	  i do like how conditional operator is very terse and can
	  do the same thing in a very small line. But it could also
	  be a bit more difficult to read and understand. It could
	  simply be a skill issue whether it's hard to read or not
	  but i am not really sure.

	  I do think the if statement is a bit easier to read because
	  it is simply just so common and widely used that you really
	  just default to it. I know that all operators and if
	  statements have their best moments to be used but i can't
	  really judge which one would be best for this case.

	  I guess the best use for the the conditional operator
	  is best when we want to do a simple if statement where there
	  are just two simple outcomes
