Does anyone know if it really needs the !!obj&& at the start? Isn't that redundant with checking that the type is either "object" or "function"? And is there a reason to use '!!' inside a conditional? Wouldn't obj&& do basically the same thing?

Unfortunately, that's not redundant, because `typeof null` returns "object": https://2ality.com/2013/10/typeof-null.html https://2ality.com/2013/10/typeof-null.html

!!null && false === false null && false === null
