Don't see the problem

Where did I trip up?

app.js 
var answer = prompt("What is the best programming language?");
if (answer === "Javascript") {
  alert("You are correct");
}
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Hey there! I'm pretty sure it's just that the "S" in JavaScript needs to be capitalized. Give that a shot.

If it makes you feel any better, these types of mistakes are guaranteed to plague your entire career as a developer. You just get better at debugging them, but they will forever remain frustrating. ...That probably didn't help at all.

Keep up the great work!

Michael,

Java*S*cript is case sensitive. This can lead to problems in your code.

Hint: see bold letter ^

Hope this helps!

The code is correct. If you are seeing errors, probably you are answering "Javascript" differently in the prompt, such as "javascript", or "JAVASCRIPT", or "javaScripT".

JavaScript is a code sensitive language, which means "JavaScript" === "javascript" will evaluate false.

To make sure you got it all right, you can try the .toUpperCase() method. This method will compare the uppercase version of the two strings. 

   if(answer.toUpperCase() === "JavaScript".toUpperCase()) {
      alert("You are correct");
   }
