util: improve internal isError()
validation
#24746
Conversation
The current internal isError function checked the toString value instead of using the more precise `util.types.isNativeError()` check. The `instanceof` check is not removed due to possible errors that are not native but still an instance of Error.

I think this should have some unit tests, specifically, some that failed before the change and succeed afterwards. My js isn't good enough, I don't understand the subtleties of how it is becoming more precise, and was hoping to learn what corner cases are better covered from the tests.
I just pushed some tests as well. |
