Why is it only console logging, 'You lost, try again?'

// 1. Get user's choice.
// USER: Rock 0; Paper 1; Scissors 2;
// COMPUTER: Rock 0; Paper 1; Scissors 2;

function getUserChoice(){
  const choices = ['rock', 'paper', 'scissors'];
  const userChoice = Math.floor(Math.random(choices) * 3);
  console.log(userChoice);
}
getUserChoice();

// 2. Get computer's choice.
function getComputerChoice(){
  const choices = ['rock', 'paper', 'scissors'];
  const computerChoice = Math.floor(Math.random(choices) * 3);
  console.log(computerChoice);
}
getComputerChoice();
