 Implement a function `determineOddEvenCards` that takes in two parameters: an array of cards (Elyse's deck), and a boolean (true is analogous to 'even', and false is analogous to 'odd').
 
 This function should return a single number: the number of odd or even cards there are (depending on the value of the second argument) in the deck.

 To practice, use a `for...of` loop in the function implementation this time.
