I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

If you have your JS code in a separate file, you can’t add an event listener to your button like you’re currently doing. You have to add it within your script file instead:

document.querySelector('button').addEventListener('click', obj.fahToCel)

Need to see more of the code (ie the htmlso can see where in the html you’re referencing the script).

Also the actual error would be helpful: open the browser console and see what the error is when you click that element.
