CC3000 not working

I just tested something else and noticed, that it works if i wrap all the wifi code in a function like this:

var wlan;

function init(){
  wlan = require("CC3000").connect();
  wlan.connect( "AccessPointName", "WPA2key", function (s) { 
    if (s=="dhcp") {
      require("http").get("http://www.pur3.co.uk/hello.txt", function(res) {
        res.on('data', function(data) {
          console.log(">" + data);
        });
      });
    }
  });
}

init();

It would be good if this gets reflected in the CC3000 manual.
