|  | Similar to the last challenge, but now we are chaining 2 functions together. It seems complicated, but it's just javascript. | ||
|  | 
 | ||
|  | Instead of responding with the time we can also add a string to the request and pass it to the next function. This is trivial, but it makes for a decent example. The code looks like: | ||
|  | 
 | ||
|  | ```javascript | ||
|  | app.get("/now", middleware(req, res, next) { | ||
|  |   req.string = "example"; | ||
|  |   next(); | ||
|  | }, | ||
|  |   function (req, res) { | ||
|  |       res.send(req.string); // This will display "example" to the user | ||
|  |   }); | ||
|  | ``` | ||
|  |
