I think Brendan had a nice explanation of that some time back:

Why packages and namespaces?

[Peter Michaux]

What it the reason for ES4 having both packages and namespaces? It
seems like both can be used to protect the global namespace from
clutter and otherwise avoid identifier clashes. When to use one and
when to use the other?

Thank you,
Peter
