JavaScript string initialization

Question

In JavaScript, from my understanding, the below are all same:

var carter2 = new String();
var carter2 = \'\';
var carter2 = \"\";

Which one is

Answer 1

Definitely without the constructor function call.

So with either single or double quotes (i.e. literal).

Note, this kind of optimization (literal vs. constructor) I believe would only matter if you had hundreds or thousands of these statements though.
