Question

Let’s say I have the following object:

var lol = {
    section: {},
    other: {foo: 'bar', foob: 'baz'}
};

Now if I do the following:

lol.section.other = lol.other;

will a reference be made linking section.other to other or will the entire other object be copied and placed in section?

Answer 1

You’re creating two references to the same object.

Javascript objects are never implicitly copied.
