Question

Define the Pokemon class using the given specifications in JavaScript(ES6)

Pokemon class specifications

1. The Pokemon class should be defined.
2. A Pokemon object should be initialized, or constructed, by passing in 5 arguments, which should correspond to the following 5 properties in order: .name, .attack, .defense, .health, and .type.
   • For example:

    const charmander = new Pokemon("charmander", 12, 8, 30, "fire");
    console.log(charmander.name);    // charmander
    console.log(charmander.attack);  // 12
    console.log(charmander.defense); // 8
    console.log(charmander.health);  // 30
    console.log(charmander.type);    // fire

   • Data type validation is not needed here. You can assume the following property:type pairings will always be used:
     • .name:string
     • .attack:number
     • .defense:number
     • .health:number
     • .type:string
3. Pokemon objects should have a takeDamage() method, which takes a number as an argument and properly reduces the .health of the Pokemon by that number.
   • Note: if the .health would go below 0, the .health should be set to 0 instead.
   • For example:

    console.log(charmander.health);  // 30
    
    charmander.takeDamage(5);
    console.log(charmander.health);  // 25
   
    charmander.takeDamage(2000);
    console.log(charmander.health);  // 0

4. Pokemon objects should have an attackOpponent() method, which takes a Pokemon object as an argument (the opponent being attacked). This method should call the takeDamage() method belonging to the opposing Pokemon and provide the appropriate damage as an argument. Damage is calculated simply: DAMAGE = CURRENT_POKEMON_ATTACK - OPPONENT_POKEMON_DEFENSE.
   • For example:

    const charmander = new Pokemon("charmander", 12, 8, 30, "fire");
    const bulbasaur = new Pokemon("bulbasaur", 7, 9, 35, "grass/poison");
   
    console.log(charmander.attack);  // 12
    console.log(bulbasaur.defense);  // 9
    // 12 attack - 9 defense = 3 damage
   
    console.log(bulbasaur.health);  // 35
    charmander.attackOpponent(bulbasaur);   // charmander attacks bulbasaur
    console.log(bulbasaur.health);  // 32

   • By default, attacking a Pokemon should do at the very least 1 damage. Consider what might happen if the Pokemonbeing attacked has a higher .defense than the .attack of the attacking Pokemon.
5. Pokemon objects should have a display() method, which takes no arguments and returns a string with the current pokemon's .name in all caps, .type in all caps and in parenthesis, and .health with a forward-slash, "/", followed by the .health the Pokemon was initialized with.
   • For example:

    const pikachu = new Pokemon("pikachu", 9, 10, 25, "electric");
    pikachu.display(); // "PIKACHU (ELECTRIC) 25/25"
   
    pikachu.health = 12;
    pikachu.display(); // "PIKACHU (ELECTRIC) 12/25"

Answer 1

java.script code for class pokemon:

<script>
class Pokemon {

constructor(name,attack,defense,health,type) {
this.name = name;
this.attack = attack;
this.defense = defense;
this.health = health;
this.ihealth = health;
this.type = type;
}
takeDamage(num){
this.health = (this.health) - num;
if(this.health < 0)
this.health = 0;
}
attackOpponent(opponent){
var damage = this.attack - opponent.defense;
if(damage < 0){
damage = 1;
}
opponent.health = opponent.health - damage;
}
display(){
console.log((this.name).toUpperCase()+" ("+(this.type).toUpperCase()+") "+this.health+"/"+this.ihealth);
}
}

const pikachu = new Pokemon("pikachu", 9, 10, 25, "electric");
pikachu.display(); // "PIKACHU (ELECTRIC) 25/25"

pikachu.health = 12;
pikachu.display(); // "PIKACHU (ELECTRIC) 12/25"
</script>
