Are variables statically or dynamically “scoped” in javascript?

Question

Or more specific to what I need:

If I call a function from within another function, is it going to pull the variable from within the calling function, or from the le

Answer 1

I would like to add that lambda expressions are also statically scoped at the location that the expression is defined. For example,

var myVar = 0;

function foo() {
    var myVar = 10;
    return { bar: function() { addMe = myVar + 10; }}
}

var myObj = foo();

var addMe = 6;
alert(addMe);

myVar = 42;
myObj.bar();

alert(addMe);

This will display 6 and 20.
