can we make console game with javascript code example

Example: javascript rpg tutorial

tChar.fight = function(enemy){
   //assumes enemy is also based on Char
   hitPerc = (this.hitPerc - enemy.defMod) / 100;
   if (Math.random() < hitPerc){
    damage = 0;
    for (i = 0; i < this.damage; i++){
     damage += parseInt(Math.random() * 6);
    } // end for
    damage -= enemy.armor;
    enemy.hp -= damage;
    if (enemy.hp <= 0){
     alert(enemy.name + " is dead!")
     document.location.href = ";
    } // end 'enemy dead' if
   } // end "hit" if
  } // end fight
