| 9 ECMA Section: 15.2.4.2 Object.prototype.toString() | |
| 10 | |
| 11 Description: When the toString method is called, the following | |
| 12 steps are taken: | |
| 13 1. Get the [[Class]] property of this object | |
| 14 2. Call ToString( Result(1) ) | |
| 15 3. Compute a string value by concatenating the three | |
| 16 strings "[object " + Result(2) + "]" | |
| 17 4. Return Result(3). | |
