Conditional statements

What is wrong with this? The code challenge checker keeps saying I've done something wrong.

var answer = prompt('What is the best programming language?'); if ( answer==='Javascript' ) { alert('You are correct!'); }

app.js 
var answer = prompt('What is the best programming language?');
if ( answer==='Javascript' ) {
  alert('You are correct!');
}

The question states: Add a conditional statement that opens an alert dialog box with the message "You are correct" when the answer contains the string 'JavaScript'.

The error is on line two: 

if ( answer==='Javascript' ) {

It should rather be 'JavaScript' with a capital letter 'S' and not 'Javascript' as in your current code.

Cheers!

Dang. I read over that again and again and didn't notice the case difference. Thanks for helping out!

It's been a while since I covered JS basics, but I think your second line in the .js file holds the problem. The '===' needs to be separated from the other words.

Hmm...I just tried that and it still says I'm getting it wrong. The program actually runs as intended first showing a prompt and then an alert box if I answer with 'Javascript'. Even though the program runs it is still marked as wrong.

It is syntactically correct. check your alert, prompt, if values. Is it equal to what treehouse says you should get?
