[thelist] What's the most reliable way to check a javascript null?

Howdy all:
I'm wondering if, in javascript:
if (Variable != "null")
if (Variable != null)
if (Variable != "")
if (Variable != '')
if (variable)
... are equivalent... And whether one is "best practice" or whether one
needs several of these tests to accommodate all browsers.
I'm writing a test case to determine whether a javascript variable exists.
Any thoughts?
Jonathan
