| File Name: boolean-001.js |
| Description: Corresponds to ecma/Boolean/15.6.4.3-4-n.js |
| |
| 15.6.4.3 Boolean.prototype.valueOf() |
| Returns this boolean value. |
| |
| The valueOf function is not generic; it generates |
| a runtime error if its this value is not a Boolean |
| object. Therefore it cannot be transferred to other |
| kinds of objects for use as a method. |
