Connecting to one of available WIFI's

Cleaning it up a bit:

The code

//ServeHello4.js  7Jan2018

//espruino board with ESP8266
//PICO  with ESP8266
//var Hardware=0; //Espruino board
var Hardware =1; //PICO
// list of Wifi and passwords
var hotspots=[

  {SSID:"faux2",key:"a6a70"}
];
var hotspot=1;
console.log(hotspots.length);
var Serial;
var Startagain=0;
var myinterval;
function test(){
if(Hardware===1)Serial=Serial2;
if(Hardware===0)Serial=Serial4;
if(Hardware===1){
 digitalWrite(B9,1); // enable on Pico Shim V2
 Serial.setup(115200, { rx: A3, tx : A2 }); //Pico
}
if(Hardware===0)Serial.setup(115200, { rx: C11, tx : C10 }); 
//espruino board
console.log("Start connection process");
var wifi = require("ESP8266WiFi_0v25").connect(Seri­al, function(err) {
 if (err){Startagain=1;return 1;}
 console.log("Reset the ESP8266");
 wifi.reset(function(err) {
  if (err){Startagain=1;return 1;}
  console.log("Try Connecting to WiFi ",hotspots[hotspot].SSID);
  wifi.connect(hotspots[hotspot].SSID,hots­pots[hotspot].key, function(err) {console.log(err);
   if (err){Startagain=1;return 1;
}
    wifi.getIP(function(l,ip){
     if (err){Startagain=1;return;}
     console.log("IP= ",ip,"\n\r"+l);
     console.log("Wi-Fi Connected");
     clearInterval( myinterval);
     var http = require("http");
     //do a server
     http.createServer(function (req, res) {
      res.writeHead(200);
      res.end("Hello World");
     }).listen(8080); //end server
  });//end getIP
  console.log("end getIP");
 });//end connect
 console.log("end connect");

  console.log("end require");
  return 0;
}//end test
function ccc(){
  var x=0;
console.log("Start");
x=test();
console.log("end test",x);
if(x!==0){
  console.log("Try again");//error seen
}
}//end cccc
myinterval=setInterval(function () {
  console.log("Test for error");
  if(Startagain){
   Startagain=0;
   hotspot++;
   if(hotspot>=hotspots.length)hotspot=0;
   console.log(hotspots[hotspot].SSID);
   ccc();
  }//end of errr
}, 2000);
ccc();
