No, you see the trends. You see that people have been looking less and less for jQuery and more and more for React.
But React hasn't reached the height of jQuery at its peak.
I would not be surprised if you're right in your assertion of what's used more for new projects. I still don't think the evidence you provided is enough to be so certain.
If I want to look up documentation for jQuery, I don't google the term "jquery" to find their docs. I just go straight to the docs directly. For a lot of situations, people's IDEs do enough work to not google something.
But that wouldn't still explain why searches for the term has decreased.
Besides, people in general do look up to the online documentation or links to the documentation from stack overflow.
It is the more reliable proxy.
