What is the difference between try-catch and Express error handling?

Can you explain the difference between try-catch and Express error handling?

Sure! Try-catch is a JavaScript construct used to handle exceptions in synchronous code, while Express error handling is specifically designed for managing errors in middleware and routes.

How does try-catch work in JavaScript?

In JavaScript, try-catch allows you to test a block of code for errors. If an error occurs, the catch block executes, allowing you to handle the error gracefully.

What about error handling in Express?

In Express, you can define error-handling middleware that takes four arguments: error, request, response, and next. This middleware can catch errors from routes and send appropriate responses.

Can you give an example of Express error handling?

Certainly! Here's a simple example:

app.use((err, req, res, next) => {
  console.error(err.stack);
  res.status(500).send('Something broke!');
});
