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.
