| 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. |
