Middleware not executing

My code is exactly like the instructor's but when I make a GET request in either Postman or firefox none of the middleware logs to the console.

This is my code:

'use strict';

var express = require('express'); var app = express();

app.use(function(req, res, next){ console.log("First Middleware!"); return next(); });

app.use(function(req, res, next){ console.log("Second Middleware!"); return next(); });

var port = process.env.PORT || 3000;

app.listen(port, function(){ console.log("Server running!"); });

Hey dude,

I don't think the instructor returns the next function. I believe he just executes it.

var express = require('express'); 
var app = express();
var port = process.env.PORT || 3000;

app.use((req, res, next) => { 
  console.log("First Middleware!");  
  next(); <-- HERE
});

app.listen(port, () => { 
  console.log("Magic is happening!"); 
});

Hope this helps.

:-)
