What is the difference between try-catch and error middleware?

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

Sure! Try-catch is a block of code used to handle exceptions in a specific section of your code, while error middleware is a function in frameworks like Express.js that handles errors globally.

When should I use try-catch instead of error middleware?

Use try-catch for synchronous code where you want to handle errors immediately. Error middleware is better for handling errors that occur in asynchronous code or across multiple routes.

Can you give me an example of error middleware?

Certainly! In Express.js, you can define an error middleware like this: app.use((err, req, res, next) => { res.status(500).send('Something broke!'); }); This catches errors from all routes.

What happens if I don't use error middleware?

If you don't use error middleware, unhandled errors may crash your application or result in unhelpful error messages to the user.
