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

I prefer to use var carter2 = ''; because:

1. It's not verbosive
2. Double quotes might clash with attributes double-quotes inside strings.

So I prefer to use single quotes in java-script, double quotes for html attributes.

UPD: this is my preference, I know that single-double quotes are interchangeable.
