Issue with my project

Hi folks,

So I am building a rock, paper, scissors game but I keep getting an undefined in my function but I am lost.

Please could someone cast an eye over and let me know where I am going wrong:

Any guidance would be appreciated as my hair is now falling out…

Cheers!!

function game(userChoice){
    const computerChoice = getComputerChoice();

    switch (userChoice + computerChoice) {
        case 'rs':
        case 'pr':
        case 'sp':
            win(userChoice, computerChoice);
            break;
        case 'rp':
        case 'ps':
        case 'sr':
            lose(userChoice, computerChoice);
            break;
        case 'rr':
        case 'pp':
        case 'ss':
            draw(userChoice, computerChoice);
            break;    
    }   
}

Thanks but I do not understand. :slight_smile:

I’ve look at your code and I’ve noticed that you call the function (let’s take win for example) like this:

win(userChoice + computerChoice); I don’t think you can pass the arguments like that you’d need to use a comma. You also do the same thing with your switch.

Yeah I tried to use , but that didn’t do anything, let me update js fiddle now!

See nothing works now - odd right?!

Can you explain the logic of your switch statement for me?

Thanks very much! I see where I was going mad… Case Closed!!! Thank you very much!!!

Switch take only one argument, so if the two variables have a value of one letter string than the switch statement was done correctly

Thanks for the help - see update fiddle https://jsfiddle.net/zn69sxbL/1/

I was going mad…

This is the solution - Issue with my project

I thought the same at first and I was going to point that out. But you can’t use any operators in switch. You can assign those values to a variable and then instead pass in that variable to the switch.

Yeah just was tired of looking at the same bit of code and not seeing the actual issue. That can happen right?! Thanks again for help :slight_smile:

Of course. Through time you’ll get better at debugging your code and deciding when to take a refresher. Before the syntax, I recommend you always check the logic of your code first. Syntax errors will be easier to fix then. Or not depends on how the actual problem reveals itself. Hopefully a not too hard problem.

Anyways I’m glad to be of help. Happy Coding!
