Using Iterator To Generate A Suite of Card Decks

const cardDeck = {
  suits: ['♧', '♢', '♥', '♤'],
  court: ['J', 'Q', 'K', 'A'],
  [Symbol.iterator]: function* () {
    for (let suit of this.suits) {
      for (let i = 2; i <= 10; i++) yield suit + i;
      for (let c of this.court) yield suit + c;
    }
  }
}

console.log(...cardDeck)
