Look at it like this:
(TL,DR: http://jsbin.com/axomev/edit ... yes, 'this' == 'window')
function fn09Wrapper() {
// same as before:
fn09();
// now ... do we have the same scope as fn09?
alert(this.op1+this.op2);
// and is that the same as window?
alert(window.op1+window.op2);
}
function fn09(){
var op1 = 2;
var op2 = 4;
this.op1 = 7;
this.op2 = 4;
function compute1(){
return (op1+op2);
}
function compute2(){
return (this.op1+this.op2);
}
alert(compute1());
alert(compute2());
}
