Variable Scope Inside A Function

I think I've had JavaScript variable scope figured out, can you please
see if I've got it correctly?

* Variables can be local or global
* When a variable is declared outside any function, it is global
regardless of whether it's declared with or without "var"
* When it is declared inside a function, if declared with "var", it's
local, if not, it's global
* A local variable that is declared inside a function is local to the
whole function, regardless of where it is declared, e.g.:

function blah() {
for(var i ... ) {
var j ...
}}

i and j will both be visible within blah() after their declaration.
* the notion of "function" in this context also applies for this kind
of construct:

var myHandler =
{
onClickDo: function()
{

in the sense that whatever one declares inside onClickDo with "var"
will only be visible inside onClickDo. What else, am I missing anything?
