[Noisebridge-discuss] GlobalScopePolluter

[Garrett Smith]

Mark asked a great question last night:

"Why do we need to know what happens when var is omitted?"

And the answer involves a quirk of MSIE's GlobalScopePolluter.

"Unsafe Names for Form Controls" article describes it a bit on the page
about globals:
jsfaq.org/notes/names/extra_props_global.html

More how GlobalScopePolluter affects non-IE browsers, even when `var` is
used:
Global Scope Polluter, copied from MSIE is and always will be problematic.
