Return global object using this keyword from function

It is not related to Javascript purely. I am using NodeJS.

var common_admin_users_param = {
    Limit:      60,
    GroupName: "admin",
    NextToken:  undefined
};

function getAdminUserParams() { 
    alert(this.common_admin_users_param); // undefined
}

getAdminUserParams();

I am wondering why it is giving me undefined.

My requirement is that my common_admin_users_param is global variable having some default values.

But i want the unique copy of this global variable for each session. So, I made function which will return current instance of this global variable.

Any help?

Code snippet: JSFiddle

(It is now working :))

Did you try `window.common_admin_users_param`? If that method is not inside a class, you cannot use `this`... – Mr. Polywhirl Apr 18 '18 at 10:24

Ah, the infamous `this` scope issue. Yet again. Google for articles explaining how `this` works. – mingos Apr 18 '18 at 10:25
I am using node js. So window will not work for me :) – Jayesh Dhandha Apr 18 '18 at 10:32
use global.yourobject = {} ; alert(global.yourobject) in node environment instead of window to make them available globally through global – Nish26 Apr 18 '18 at 10:48
