Simply :

console.log(window.number);

From the MDN :

Global variables

Global variables are in fact properties of the global object. In web pages the global object is window, so you can set and access global variables using the window.variable syntax.

But you shouldn't have to do this. If you need to go around shadowing, you have a design problem and you should probably fix it.

you should be able to call

window.number

A global variable is really just a property of the window object.
