| 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
 | |
|   });
 | |
| ```
