anonymous-objects

Anonymous objects in JavaScript refer to objects that are created without being assigned to a specific variable or name. They are typically used temporarily for a single purpose, often as arguments when calling functions or for on-the-fly data organization. These objects lack a defined identifier and are constructed and used directly within the code where needed. 


class Card {
  constructor(value, suit) {
    this.value = value;
    this.suit = suit;
  }
}

let cards = [
  new Card("A", "Hearts"),
  new Card("A", "Spades"),
  new Card("A", "Diamonds"),
  new Card("A", "Clubs"),
  new Card("10", "Hearts"),
  new Card("10", "Spades"),
  new Card("10", "Diamonds"),
  new Card("10", "Clubs"),
];

//anonymous objects can be refernced by an index number
//display all - method I
cards.forEach((card) => console.log(`${card.value} of ${card.suit}`));
//display all - method II
function displayAll(cards) {
  for (let i = 0; i < cards.length; i += 1) {
    console.log(`${cards[i].value} of ${cards[i].suit}`);
  }
}
