plus it's a bad design. you allready take a callback, but the callbakc have
to know about your whole module. plus this way all users get the same
token, and if you want to change it, you have to break your api. better do
this:
----------------------------------------------------
var token = "";
function genToken(callback) {
token = "blabla";
callback(*token*);
}
module.exports.genToken = genToken;
----------------------------------------------------
-----------------------------------------------------
var login = require("./login");
*var aquiredToken = ''*
function continuef(*token*) {
*aquiredToken = token*
console.log("Token is:" + *aquiredToken*);
}
login.genToken(continuef);
-----------------------------------------------------
