Question

So there is no way to remove access to an

exposed variable from the global scope in the browser except iife?

After I wrote a bunch of exposed variables without iife,

The I tried to remove them from the global scope by

window.variable = undefined;

After I have added them to a general object and export them.

I created another javascript file just below the first one, and created with content of

const variable = someOtherValue

,

What I want to achieve is to remove variables from the global scope without iife
