well, it's not true really. In the following example x will have global scope and y will be local to its function:
x=2;
function test() {
y = x + 3;
}

That's quite wrong. Both y and x will be global scope. You just declare y with "var" in order for it to be a function scope variable.
The major problem with Javascript is that it is a hodge-podge of different languages mixed together where the semantic syntax is "C-like"; so you get a bunch of programmers who are arguing over the logic of scope when they really don't understand the rules of the language well enough.
