Can I reference other properties during object declaration in JavaScript?

Question

Answer 1

No. this in JavaScript does not work like you think it does. this in this case refers to the global object.

There are only 3 cases in which the value this gets set:

The Function Case

foo();

Here this will refer to the global object.

The Method Case

test.foo(); 

In this example this will refer to test.

The Constructor Case

new foo(); 

A function call that's preceded by the new keyword acts as a constructor. Inside the function this will refer to a newly created Object.

Everywhere else, this refers to the global object.
