Answer 1

parent is not a function. It is an object most probably a window object. And a child object inside that is referenced by using the code.

See

window.parent

Returns a reference to the parent of the current window or subframe.

If a window does not have a parent, its parent property is a reference to itself.

When a window is loaded in an , , or , its parent is the window with the element embedding the window.

Answer 2

If you want to know if an object has a "document" property that is a document node, you can do:

(typeof obj.document == "object" && obj.document.nodeType == 9)
