You may want to try to use VSCode's code formatting function (press CMD/CTRL + P, then enter "> format" at the prompt box)
Are you deleting an element from the people array? Did you miss capturing the id from url?

Many thanks for noticing - I've finished it now! Didn't know about CTRL + P + '> format', will learn more about this toll now. Thank you!

assign port number in a variable so you can refer to it in your console message.

What if no message with the specified id is present? Also, what if the provided "id" is not an integer?

Wow, didn't think about it. Added if (messageIndex === -1) { return res.status(404).send({ error: "Message not found" });} and
if (isNaN(id)) {return res.status(400).send({ error: "Invalid ID" });}
Do you think it's a good way to address these issues, or is there a better way?

you can listen to port specified by process.env.port when it is present or port 9090 by saying
app.listen( process.env.port || 9090,
Again, its better to use a variable to store the default port number 9090

I dont have definite answers to your question but just want to highlight the importance of
- Input validation
- Error handling
I think Alun's material provided examples on the above aspects. You may take a look
