What is the significance of the next function in error-handling middleware in Express?
- It sends a response to the client
- It terminates the application
- It passes control to the next middleware
- It logs the error
In Express.js, the next function, when called within an error-handling middleware, passes control to the next middleware in the chain. This is essential for the error-handling flow, as it allows you to continue processing additional error-handling middleware or routes. It does not send a response to the client or terminate the application, but it facilitates the flow of handling errors.
