Can anyone explain?

Question

var x = 3;
var one = {
x: 2,
two: {
x: 1,
three: function() {
return this.x;
}
}
}
var go = one.two.three;
console.log(go(), one.two.three());

Answer 1

`var go`
Use of 'var' here indicates that variable <go> is stored as an attribute of 'window' object. For this reason when <go> is invoked, <x> refers the one in 'window' object context. That is the one registered by `var x = 3;`

But when the 'three' method is invoked directly, <x> refers to a member of object 'two'.

I guess that's about it
