// A LESS TRITE EXAMPLE

// we might make an object to use in a game, for example let's think of 
// Pokemon

function Pokemon(options) {
  this.name = options.name;
  this.hp = options.hp;
  this.moves = options.moves;

  this.attack = function() {
    return this.moves[Math.floor(Math.random()*2)];
  }
}

var charmander = new Pokemon({
  name: "charmander",
  hp: 300,
  moves: [
    {name: "scratch", hp: 100},
    {name: "fire blast", hp: 400}
  ]
});

var squirtle = new Pokemon({
  name: "squirtle",
  hp: 200,
  moves: [
    {name: "tackle", hp: 200},
    {name: "surf", hp: 300}
  ]
});

var pikachu = new Pokemon({
  name: "pikachu",
  hp: 400,
  moves: [
    {name: "quick attack", hp: 200},
    {name: "thunderbolt", hp: 400}
  ]
});

function battle(pokemon1, pokemon2) {
  var attack1 = pokemon1.attack();
  var attack2 = pokemon2.attack();
  if (attack1.hp > pokemon2.hp ) {
    return pokemon1.name + " attacked with " + attack1.name + " and defeated " + pokemon2.name;
  } else if (attack2.hp > pokemon1.hp) {
    return pokemon2.name + " attacked with " + attack2.name + " and defeated " + pokemon1.name;
  } else {
    return "it's a tie!";
  }
}

The max random move number should be the length of the moves array.

This is rad.
