What is wrong with this code?

What is wrong with this code that wont allow the answer to be blue?

function colorGuess() {
    var question = prompt('What is your favorite color?');
        if (question.toUpperCase === 'BLUE') {
            alert('That is my favorite color');
        } else {
            alert('That is a nice color, but my favorite is blue!');
        }
}
colorGuess();

toUpperCase is a method of String prototype not property. Doing something like 'a'.toUpperCase will return identifier of function. You can fix this by calling the function with '()'.

So question.toUpperCase -> question.toUpperCase()
