9 ECMA Section: 15.5.1 The String Constructor called as a Function |
|
10 15.5.1.1 String(value) |
|
11 15.5.1.2 String() |
|
12 |
|
13 Description: When String is called as a function rather than as |
|
14 a constructor, it performs a type conversion. |
|
15 - String(value) returns a string value (not a String |
|
16 object) computed by ToString(value) |
|
17 - String() returns the empty string "" |
