ECMA Section: 15.5.2 The String Constructor
15.5.2.1 new String(value)
15.5.2.2 new String()
Description: When String is called as part of a new expression, it
is a constructor; it initializes the newly constructed
object.
- The prototype property of the newly constructed
object is set to the original String prototype object,
the one that is the intial value of String.prototype
- The internal [[Class]] property of the object is "String"
- The value of the object is ToString(value).
- If no value is specified, its value is the empty string.
