var name and window.name

Question

If I define a JavaScript global variable called name, does that hide the window.name property?

I ask this in the context of the Facebook JavaScript authentication API, since I noticed that having a global of that name would break it, and also since I see that window.name is used in their code.

Answer 1

If name is a global variable, then name and window.name are equivalent.

Global variables and functions are members of the global object. In browsers, the global object contains a window member whose value is the global object.
