These will work and are totally fine, but it's probably more idiomatic to do this:

assert.ifError(err);

This is OK, but is probably better like this:

assert(err instanceof Error);

Even better if the type of error is known. For example, if it's expected to be a RangeError, then assert.(err instanceof RangeError) etc.

LGTM if CI is green, although if you want to make the changes in the nits I left, even better.

I suspect that ideally status should be renamed err and treated like the err object (using assert.ifError() rather than checking for equality to null). I wouldn't hold this up over that. Might make a good next contribution, though. (If you do want to change it in this PR, though, go for it!)

Looks like this broke the CI on Windows. Fix in #10840.

This does not land cleanly in LTS. Added dont-land label. Please feel free to manually backport

If it is backported please include #10840
