I'm trying to create the rock, paper, scissors task from The Odin Project. When I run the code, the computerPlay function name shows a random number from 0-2 because of the Math.random function. How do I turn 0-2 into the choices ['rock', 'paper', 'scissors']?
let playerScore = 0;
let computerScore = 0;
const choices = ['rock', 'paper', 'scissors'];
function computerPlay() {
let computerResult = [Math.floor(Math.random() * choices.length)];
return computerResult;}
console.log(`Player Score: ${playerScore}`);
console.log(`Computer Score: ${computerScore}`);
console.log(computerPlay());let playerScore = 0;
let computerScore = 0;
const choices = ['rock', 'paper', 'scissors'];
function computerPlay() {
let computerResult = [Math.floor(Math.random() * choices.length)];
return choices[computerResult];
}
console.log(`Player Score: ${playerScore}`);
console.log(`Computer Score: ${computerScore}`);
console.log(computerPlay());I think you mean this. The computerResult would be used as the index of the choices array. (0 => rock, 1 => paper, 2 => scissors)
So, you return the value of the array at that index.
Alternative version without passing an array index (which also works):
let playerScore = 0;
let computerScore = 0;
const choices = ['rock', 'paper', 'scissors'];
function computerPlay() {
return choices[Math.floor(Math.random() * choices.length)];
}
console.log(`Player Score: ${playerScore}`);
console.log(`Computer Score: ${computerScore}`);
console.log(computerPlay());Just add choices
let computerResult = choices[Math.floor(Math.random() * choices.length)];
try to run the code below
let playerScore = 0;
let computerScore = 0;
const choices = ['rock', 'paper', 'scissors'];
function computerPlay() {
let computerResult = choices[Math.floor(Math.random() * choices.length)];
return computerResult;}
console.log(`Player Score: ${playerScore}`);
console.log(`Computer Score: ${computerScore}`);
console.log(computerPlay());
