iterator_to_arrayor "populate an array", when not all items need to be copied.
- use clone operator, cloneNode method or import method?
documentElement::method? (see here)
replaceChild, no avoids "side effects"?
My position, today, is only "do an arbitrary choice and follow it in all implementations" (like a "Convention over configuration" principle)... But, there are another considerations? About performance, there are some article showing benchmarks?
