Section: Function.toString
|
|
Description:
|
|
|
|
Since the behavior of Function.toString() is implementation-dependent,
|
|
toString tests for function are not in the ECMA suite.
|
|
|
|
Currently, an attempt to parse the toString output for some functions
|
|
and verify that the result is something reasonable.
