Javascript help


i really need help here on this exercises for building grade book app , the last step im stuck for one more function

Photos/screenshots of an error can be helpful, but it also helps to provide the complete code. Posting the code helps us help you better!

When you enter a code, 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 (').
