In Express.js, how can you handle errors occurring in asynchronous code within a route handler?
- try-catch
- next(error)
- return error;
- res.error(error)
In Express.js, you can handle errors occurring in asynchronous code within a route handler by calling next(error). This passes the error to the error-handling middleware or the default error handler, allowing you to centralize error handling. Using a try-catch block won't catch asynchronous errors, and the other options are not standard practices for error handling in Express.js.
