Can you s/ns/value/? All functions call it that except this one.

This line should rather go along with the value checks at line 571.

i'm not quite sure how to do that, should i make another formatObject function like formatNamespaceObject?

Yes, that would be the ideal way here. That way there is no performance impact on regular objects.

i'll move it for consistency, but just for the record the isModuleNamespaceObject check still happens either way, there is no perf difference.

I am not sure how V8 optimizes the loop in this case. I guess it could be smart to remove the isNs check but otherwise there would be a minor overhead.

array === 0 will always be true.

I am somewhat surprised that the keys are exposed even though accessing them throws. I guess that is done by design - out of curiosity: would you be so kind and point me to the reasons why this is done like that? After looking at the test again, I see why it throws.

even though we know the export names, they aren't yet intialised (think console.log(a); const a = 1). there is no js value that can represent this state so v8 throws a reference error, which is what would happen with that example.

Not a fan of copy pasting this part. It could easily get out of sync if anything small changes.

@addaleax thanks for starting the benchmark. If they turn out to have a impact I would like to only show this when |

It would be nice to move this down to the last else because it is probably one of the least used values and does not need to be performant.

Please do not use a default value and just explicitly pass through the value.

This could now be rewritten to: if (foo) return ... if (bar) return ...
