var arr;
CreatecheckPassword: function() {

                var pas = document.getElementById("pos-password")

                var user = new db.web.Model("res.users").get_func("read")(this.session.uid, ['password']).pipe(function(result) {
                     arr = result.password;
                     alert(arr);//prints the expected value
                });
                alert(arr);//prints nothing
},

jslint or jshint is your friend. Get it and use it on your code to get lint messages.
