Not OP (and I don't use it for this case), but I suspect that the instructional "how do you do X" videos that supplanted the "look up the blog post" of even longer ago.

"How do you start a react application" and going to https://www.youtube.com/results?search_query=How+do+you+star... (incognito or private session suggested to avoid search history getting you react application suggestions for the next several months) and watching those videos.

For many people looking for a guide, they've switched to an LLM which gives them a more tailored experience.
