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":

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