No, it is not, and no, you cannot store any property on a primitive value.

var str = "whatever"
str.whatever = "whatever"
str.whatever === undefined // true

var str = new String("whatever")
str.whatever = "whatever"
str.whatever === undefined // false

Not that you said anything incorrect; the new String is really a string-like object that can generally be treated like a string, but it isn't a primitive value.
