What are some common errors in Express.js?

Some common errors in Express.js include middleware not being used correctly, route handling issues, and improper error handling.

Can you give me an example of middleware errors?

Sure! A common middleware error is forgetting to call next() in your middleware function, which can prevent the request from moving to the next middleware or route.

What about route handling issues?

Route handling issues often arise from incorrect path definitions or not matching the HTTP method, like using GET instead of POST.
