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. 38 39 Author: christine@netscape.com 40 Date: 1 october 1997 41*/ 42 43 var SECTION = "15.5.2";
