I'm developing a node.js application to get an ip address from a variable located in the cloud. Later I want to use it to establish a TCP/IP connection with a server. This is the code I'm using:

...
var settingsip;
photon.get("ipAddress", function(response) {
    settingsip = response.result;
    console.log("Photon IP is:", settingsip);
  });

console.log("Photon IP2 is:", settingsip);
...

But the output which I'm obtaining is:

Photon IP2 is: undefined
Photon IP is: 10.230.89.118

Which is the problem for not getting the right value of settingsip when printing it as IP2?

You'll need to read more on the async nature of Node. The problem here is that console.log runs before your photon.get. Check out http://stackoverflow.com/questions/2353818/how-do-i-get-started-with-node-js/5511507#5511507 – Jonah Williams Nov 18 '15 at 14:42
Did you not find it odd that ip2 logged first? – Kevin B Nov 18 '15 at 16:04
