  1. The convertMarkdown function should use regular expressions to convert the markdown input from #markdown-input into HTML and should return a string containing the HTML code.

[ReferenceError: convertMarkdown is not defined]

Please re-read the above user story carefully. Your code is throwing an error because convertMarkdown() returns undefined.

Thank you for your time to reply. I have been struggling to find out why this gives me error.

I focused on the function error and found out that instead of using
<script src="script.js"></script> in html,

I’ve been using <script type="module" src="script.js"></script>
which gives the error. Now i solved the problem #1 to 6. Thank you! ``
