Were the quotes you have around the statement actually in the program? If so, that would have created a string literal instead of a program statement, and would explain why you did not see the prompt.

Also, when you call this function, you would normally want to catch the return value in a variable to use later. So a typical code line with this function might look like this:

var answer = prompt('Hello');

For future reference: when asking a question about something in a course, it can help to get a better answer if you include a link to the course page in your question. If the page has a "Get Help" button on it, you can use that to create a question and it will create a link for you, and also copy any code you were working with into the question.

You can't share a direct URL to your workspace, it's temporary and only exists while you are using it.

But you can use the snapshot function in the workspace and provide the link to that.

Wow that's a lot more code! Are you sure this is for the same question?

But anyway, the code in the repo seems to be missing a closing brace after line 36:

    wrong.push(question);
  }  // <-- add this brace

But for future issues, a workspace "snapshot" is much handier for analysis!
