Thank you, appreciate it!
FWIW I _have_ written actual code in the libraries too :) I wrote React-Redux v7 by myself, shepherded the design of our hooks API in 7.1, and did all the coding work for v8. Also created Redux Toolkit, added a couple additional APIs, and a bunch of other stuff :)
I can't speak to his code contributions, but in terms of documentation, tutorials, and community engagement, most open source projects would be lucky to have similarly prolific contributors.
