Can't pass challenge in Chrome?

I've made following code

var answer = prompt('What is the best programming language?');
if(answer){
    if( answer.toUpperCase() === 'JAVASCRIPT' ) {
        alert('You are correct');
    } else {
        alert('nest');
    }
}

Normally it didn't need if(answer) first when following the video tutorial but when not adding this you get an error in Chrome. Then when needing to do the equals JAVASCRIPT part the test will report it's not OK while it really is... I think this validation should be fixed by TeamTreeHouse?

Here is the answer, I just passed the challenge with this code: 

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

 if( answer === 'JavaScript' ) {
        alert('You are correct');
    } else {
        alert('JavaScript is the best language!');
    }

unless you are referring to a different challenge...but this is the answer to the challenge that this post is linked to...

Indeed this works, I see where I went wrong. Instead of comparing to JavaScript I compared to Javascript and then the Bummer message told me 'Comparing strings is case sensitive. So 'Javascript' or 'javascript' is not equal to 'JavaScript'. That's why I started using the toUpperCase() etc.

But thanks to your solution I saw the S was also in uppercase. Thanks

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

 if( answer === 'JavaScript' ) {
        alert('You are correct');
    } else {
        alert('JavaScript is the best language!');
    }

That's all you need.

I know this should be the answer but it isn't, I exactly copied your and it does not pass . It will say that Task 1 is not correct anymore and when using Developer tools you'll see there's an error

You dont need if(answer), or toUpperCase() per the challenge instructions... All they want you to do is test if the answer is equal 'JavaScript'...if it is, then alert 'You are correct', if not, then alert 'JavaScript is the best language'. You are adding a little more than they wanted you too.
