var compare = function(choice1) {
    var winSound = document.getElementById('./sounds/Applause.mp3');  
    var lostSound = document.getElementById('./sounds/Fail.mp3');
    var computerChoice = Math.random();
    if (computerChoice < 0.34) {
        computerChoice = "rock";
    } else if(computerChoice <= 0.67) {
        computerChoice = "paper";
    } else {
        computerChoice = "scissors";
    }
    if (choice1 === computerChoice) {
        return('The result is a tie!');
      }
    else if (choice1 === 'rock') {
        if (computerChoice === 'scissors') {
           result = 'You are the winner.' + winSound.play();
        } else {
            return 'Computer is the winner.';
        }
    }
    else if (choice1 === 'paper') {
        if (computerChoice === 'rock') {
            return 'You are the winner.';
        } else {
            return 'Computer is the winner.';
        }
    }
    else {
        if (computerChoice === 'rock') {
            return 'You are the winner.';
        } else {
            return 'Computer is the winner.';
        }
    }
};

var game = function(choice1) {
    document.getElementById('result').innerHTML = compare(choice1);
};

Answer 1

You create an audio object:

var audio = new Audio();

Then assign the src to the sound you want to play in your callback, and play:

audio.src = './sounds/Applause.mp3';
audio.load();
audio.play();

return(text);

You may want to cache the sounds beforehand so that there is no delay.
