Strange behaviour of http.createServer

Attached code runs fine, but after moving everything into an object, by removing comments, fails with this error.

*Uncaught Error: Function "listen" not found!
at line 13 col 10

  }).listen(8080);*

Got this problem on ESP32, could not test on other board. @Gordon, if this is an ESP32 only problem, please move it to that category :-)
Tested this 10 times with both options and always got same result.

var wifi = require("Wifi");var http = require("http");
var ssid = "xxxxxxx";
var password = "yyyyyyyyyyyy";

//function httpSrv(){
  function init(){
    var x;
    wifi.connect(ssid, {password: password}, function(dt) {
      http.createServer(function(req,res){
        res.writeHead(200);
        res.end("Hello World");
      }).listen(8080);
    });
  }
  init();
//}
//var s = new httpSrv();

It fails on linux too.

It's because http.createServer returns an object of class httpSrv. If you then overwrite that built-in class with your own function, magically all the built-in methods of httpSrv disappear.

It's not a bug, it's just part of JS. Rename httpSrv to httpServer and it'll be fine :)

Sometimes life can be so easy, once you know how to live.
Thanks a lot, a "many-hours-without-success-story" comes to an end ;-)
