  • Guest, before posting your code please take these rules into consideration:
    • It is required to use our BBCode feature to display your code. While within the editor click < / > or >_ and place your code within the BB Code prompt. This helps others with finding a solution by making it easier to read and easier to copy.
    • You can also use markdown to share your code. When using markdown your code will be automatically converted to BBCode. For help with markdown check out the markdown guide.
    • Don't share a wall of code. All we want is the problem area, the code related to your issue.

Code: 
do {
        let playerMove = prompt('Please enter your move', 'e.g rock, paper or scissors');
        let computerMove = ['rock', 'paper', 'scissors'];
        
        switch (playerMove){
            case 'rock':
                document.querySelector('p').innerHTML= computerMove[Math.floor(Math.random()*3)] + ' vs  your rock';
                break;

This is cleaner, and works :

Code: 
do {
    let playerMove = prompt('Please enter your move', 'e.g rock, paper, or scissors').toLowerCase();
    let computerMoveOptions = ['rock', 'paper', 'scissors'];
    let computerMove = computerMoveOptions[Math.floor(Math.random() * 3)];

    switch (playerMove) {
        case 'rock':
            document.querySelector('p').innerHTML = `${computerMove} vs your rock`;
            break;
        case 'paper':
            document.querySelector('p').innerHTML = `${computerMove} vs your paper`;
            break;
        case 'scissors':
            document.querySelector('p').innerHTML = `${computerMove} vs your scissors`;
            break;
        default:
            document.querySelector('p').innerHTML = 'You need to learn how to play Rock, Paper, Scissors';
    }
} while (confirm('Wanna play again?'));
