Who's on JavaScript?

If you like JavaScript this binding, and the comedy classic Who’s on First?, then is this the mashup for you!

INT. OFFICE - DAY

Two programmers, Phil and Mary, sit at their desks, typing. After a moment, Phil turns to Mary, and shows her a piece of code, which looks like this:

 1function showInfo() {
 2  return this.name + ' is ' + this.age + ' years old, and has fought ' + this.fights + ' bears.';
 3}
 4
 5var person = {
 6  name: 'Sally',
 7  age: 43,
 8  fights: 16,
 9  showInfo: showInfo
10};

PHIL

Hey Mary, you're the JavaScript expert, could you help me learn a few things?

MARY

Sure, what do you want to know?

Phil points to line 1.

PHIL

What's this?

Mary points to line 5.

MARY

That.

Phil points again to line 1.

PHIL

No, I want to know what this is.

MARY

I know. It's that.

She points again to line 5.

PHIL

This

(points to line 5)

isn't this!

(points to line 1)

MARY

Yes it is.

Phil points to both line 1 and line 5.

PHIL

These are two separate things!

MARY

Well, sure.

PHIL

Right, then what's this?

Phil points to line 1.

MARY

That.

She points to line 5.

PHIL

Okay, fine! What this?

He points to line 5.

MARY

Window.

PHIL

What? Where?

MARY

Nowhere, it hasn't been called.

PHIL

Then how the hell is that

(points to line 5)

window?

MARY

Oh, that's not window, that's an object.

Phil points to line 5.

PHIL

But you just said this is window!

MARY

Yeah, that's true.

Phil points to line 5.

PHIL

Then this is window!

MARY

No, I told you, that is an object.

PHIL

What?

MARY

Look, it's all quite simple.

She points to line 5.

MARY

That is an object.

She points to line 5.

MARY

And this is window.

PHIL

They're the same thing!

MARY

Only according to typeof.

PHIL

What?

Slow fade out as they continue to argue.

The end.
