// Make a Dice constructor that takes a numberOfSides. Add a method called roll that randomly returns a number from 1 up to the numberOfSides.
// Modify your roll method to record the returned side in a lastRoll property.

// Modify your roll method to record the returned side in a lastRoll property.


// Make a CardDeck constructor that returns an object with a cards property that is an array of 52 numbers, 1..52.
// Write a method called deal that randomly returns a number from cards and removes it from the cards array.
// Write a method called isFull that returns true or false if all 52 cards are present.
// Write a method called cut that randomly picks an index and returns an array of two arrays where the deck was split at that index.
// BONUS: write a shuffle method that mixes up all the cards. How does this change your deal method?
