ReferenceError: yes is not defined

I am learning to code javascript, and have written this code

var userAnswer = prompt("are you feeling lucky, punk?");
if (userAnswer === yes)
{
console.log("Batman hits you very hard. It's Batman and you're you! Of course Batman wins!");
}
else
{
console.log("You did not say yes to feeling lucky. Good choice! You are a winner in the game of not getting beaten up by Batman.");
}

But when I run it, I get ReferenceError: yes is not defined.

You are trying to compare the variable userAnswer with another variable yes. The problem is that you have not defined yes. I believe you are trying to compare userAnswer with the string literal "yes".

So if you changed userAnswer === yes to userAnswer === "yes" it should do what you want.

When you don't enclose yes in quotes (i.e. a string literal), JavaScript looks for a variable with the name yes. You haven't defined a variable with the name yes, so it throws your error.

Add quotes as such to determine if userAnswer contains the string yes:

if (userAnswer === 'yes')

If you want to accept different cases (i.e. Yes and YES), you can use .toLowerCase()

if (userAnswer.toLowerCase() === 'yes')
