Question
What function arguments are available to express.js route handlers?
Answers
The arguments available to an Express.js route handler function are:

req - the request object
res - the response object
next (optional) - a function to pass control to one of the subsequent route handlers

The third argument may be omitted, but is useful in cases where you have a chain of handlers and you would like to pass control to one of the subsequent route handlers, and skip the current one.   Your Comment
