Very basic Javascript classes for handling a pokerdeck.

pokerdeck.js

class card{
  constructor(value,suit){
    this.value = value;
    this.suit = suit;
  }
  get valueName(){ return this.value.toString() };
  get name(){return this.valueName + ' of ' + this.suit;}
  toString(){ return this.name }
}
class pokerCard extends card{
  get valueName(){
    if(this.value === 1)return 'Ace';
    if(this.value === 11)return 'Jack';
    if(this.value === 12)return 'Queen';
    if(this.value === 13)return 'King';
    return this.value.toString();
  }
}
class deck{
  constructor(){
    this.cards = [];
  }
  shuffle() {
    for (let i = this.cards.length - 1; i > 0; i--) {
      const j = Math.floor(Math.random() * (i + 1));
      [this.cards[i], this.cards[j]] = [this.cards[j], this.cards[i]];
    }
    return this;
  }
  get cardNames(){
    let cards = [];
    this.cards.forEach(card=>{
      cards.push(card.name);
    });
    return cards;
  }
}
class pokerDeck extends deck{
  constructor(){
    super();
    this.reset();
  }
  reset(){
    this.cards = [];
    let suits = this.suits;
    for(let j=0;j<suits.length;j++){
      for(let i=1;i<=13;i++){
        this.cards.push(new pokerCard(i,suits[j]));
      }
    }
    return this;
  }
  get suits(){return ['Spades','Hearts','Clubs','Diamonds']}
}
