of course.. :-) I'm not sure what we're talking about here because it's not very obvious where this number comes from. Is it the YouTube API, excluding React?

of course.. :-) I'm not sure what we're talking about here because it's not very obvious where this number comes from. Is it the YouTube API, excluding React? If you're thinking of using a React library, we have to assume you're already using React. Mentioning line count is useless unless you're someone intending to explicitly manage that code. But if so, why stop at 40k? It seems more constructive to talk about the size impact in megabytes or loading time of requiring the YouTube API just to have video playing in the background vs just just hosting your own static video alongside the html. Of course assuming you already use React.
