Huh? To a lot of us, that’s not an either/or question. It’s just weird. But that’s because you are on one side of the canyon or the other. You either understand both of those technologies well enough to know what they do and how they are or aren’t related. Or, you don’t understand either of them so it doesn’t matter. There is a weird area in the middle where you understand just enough to be confused.
I find this type of stream-crossing confusion to be one of the most common types of confusion for beginners. It’s not confusion about a single technology, it’s how they combine.
