is this really a discussion forum about codemirror?

thought this is a page where you can help others in codemirror but no one answering if you asked a question, lol

That’s probably because the question strongly suggests you didn’t do enough homework to understand what the project does. (Assuming this is the question you’re referring to, you’re assuming that a code editor is going to evaluate code for you, which doesn’t make much sense.)

But even if you ask good questions, no one is obliged to answer them for you. So don’t spam the forum with complaints.
