A little bit of plain JavaScript can do a lot

Neat solution - out of curiosity though, why remove the properties from the passed options? If I called that function, I wouldn't normally expect it to mutate my arguments like that.

At a glance, they do it so that at the end they can merge in any remaining props they didn't handle after all their work building `elem` is done.

This can be accomplished non-destructively with destructuring.

    const {
      attributes,
      classList,
      style,
      ...rest
    } = p

    // elem = ...consume attributes, classList, style...

    return Object.assign(elem, rest)

This approach with destructuring is great but you will need to transpile the code if you're targeting IE11 which is still often the case in enterprise settings unfortunately.
