Help a JS virgin find that sweet spot

I'm practicing JS by trying to make a rock, paper, scissor game. 

I have failed.

Can /prog/ help a nigga out?

Everything is appreciated, just keep in mind I'm new as fuck to programming.

var choice = ['rock', 'scissor', 'paper'],
    player = choice.indexOf(prompt('choose rock paper scissor')),
    computer = ~~ (Math.random() * 3);

if (player === -1) throw new Error('fuck you niggar !!');

console.log(
  choice[player] + ' vs ' + choice[computer] + ': You ',
  Math.abs(computer - player) === choice.length -1 ? 'lose' : //roll over
  player === computer ? 'tie' :
    player < computer ?
    'win' :
    'lose'
);
