creating an javascript object at global level

Question

I am trying to create an object like below

var x = function x() {};

Does this create an object at window level/global level.Is it good way of using it ?

Without the surrounding code there is no way to answer that. If you use window.x = function() {} then it will be global. — Reinstate Monica Cellio

If this was written in the global name space.. meaning in a loaded script directly or in a script tag this will be global.

But if this was made inside, for example, a dom ready event or an onlad event handlers this wont be global.

Using window.variable makes it global even if you're inside any block.
