Understanding "this" keyword

Question

What will be output?
var x = 3;
var foo = {
x: 2,
baz: {
x: 1,
bar: function() {
return this.x;
}
}
}
var go = foo.baz.bar;
console.log(go());
console.log(foo.baz.bar());

Answer 1

When you declare the go, the "this" scope refers to the global scope. That's why it returns 3. The other one is self explanatory.

Answer 2

x=3 is of global scope and hence the first call returns 3.
The second accesses the internal variable x=1 SO 3,1🤔

Answer 3

Is this still the current object?

Answer 4

3,1

Answer 5

1,1

Answer 6

It's already explained, the answer is
3,1

Answer 7

Prometheus [EXAMS]🇸🇬 by "global" do you mean a value that isn't in a function? Cause that's the only way I seem to understand it.
