Step 4 of defineProperty calls the [[DefineOwnProperty]] internal method
|
||
|
|
of O passing 'true' for the Throw flag. In this case, step 3 of
|
||
|
|
[[DefineOwnProperty]] requires that it throw a TypeError exception when
|
||
|
|
current is undefined and extensible is false. The value of desc does not
|
||
|
|
matter.
