The .toUpperCase() method is attempting to be called on the answer variable but needs the parenthesis to be called. Like this

var answer = prompt("What is the best programming language?");

if (answer.toUpperCase() === 'JAVASCRIPT') {
  alert('You are correct!');
}

I went into the first code challenge itself to test this out and I was able to recreate your problem. The code challenge won't pass when adding the .toUpperCase() method as the question isn't asking for that. I was able to pass the code challenge without adding the .toUpperCase() method and using the same capitalization in the condition as the question states. 

var answer = prompt('What is the best programming language?');

if (answer === 'JavaScript') {
  alert('You are correct');
}

So, while you code appears to be written with the correct syntax, you're going above and beyond what the question is asking and the code challenge won't pass that way. Hope this helps!

I tried to get it to pass (with your code and mine, several variations) and also ran across the same problem. Either it's a glitch, or I'm out of practice with JavaScript. Sorry I couldn't help.
