There are plenty of tutorials for == and === so please don't guide me to a basic tutorial, my question is a bit more specific:

For example http://www.w3schools.com/jsref/jsref_obj_string.asp states that:

Syntax:

var txt = new String("string");

// or more simply:
var txt = "string";

Good, but what about this?

alert(new String("a") == new String("a")); // false
alert("a" == "a"); // true

var a = new String("a");
var b = new String("a");
alert(a == b); // false

var c = "a";
var d = "a";
alert(c == d); // true

alert(c === d); // true
alert (a === c); // false

Of course nobody calls new String() anyway, but is it something about the equality failing because new String() is handled as an object not as a string?

And of course W3Schools is not the most trusted source but I would have expected all of the above alerts to say true.

Please explain.
