  24     ECMA Section:       15.5.2 The String Constructor
  25                                 15.5.2.1 new String(value)
  26                                     15.5.2.2 new String()
  27
  28     Description:        When String is called as part of a new expression, it
  29                     is a constructor; it initializes the newly constructed
  30                     object.
  31
  32                                 - The prototype property of the newly constructed
  33                                 object is set to the original String prototype object,
  34                                 the one that is the intial value of String.prototype
  35                                 - The internal [[Class]] property of the object is "String"
  36                                 - The value of the object is ToString(value).
  37                                 - If no value is specified, its value is the empty string.
