Question

I thought the syntax:

var a, b, c = {};

would mean that the three variables are separate, not references to the same {}.

Is this because {} is an object and this is the standard behavior?

So if I do:

var a, b, c = 0;

the three would indeed be separate and not references?

Thanks,

Answer 1

They shouldn’t be the same, no. Only c will be assigned the value.

a and b would just be declared, but not initialized to anything (they’d be undefined). c would, as the only one of them, be initialized to {}

Perhaps it’s clearer when written on several lines:

var a,      // no assignment
    b,      // no assignment
    c = {}; // assign {} to c
