Please Please update it , I am already following the old one right now
Love bob but redux docs are great on their own. His courses are really good but way too lengthy.
Modern redux already does alot of heavy lifting so it cuts down on the lines of codes u write. I will highly recommend stephen grinder course on modern react +redux. I didnt complete it but looking at how he teaches and the curriculum also the latest update he had, I would say its pretty complete.
On the side note I also realised a lot of these web dev courses are just a waste of time and the best way to learn is to follow their docs and build something. Only leverage on courses if you cant grasp the docs. Nowadays some docs now have crash tutorials and redux have the best docs imo. Aside from DSA/System design/UI courses I would highly advise to learn from building. Only fallback on a course if you cant follow through the official docs.
Literally with redux, u can just copy paste from their docs and then adjust accordingly. U dont even need to know what thunks are with rtk-query which integrates seamlessly with 1-2 line of code to ur root reducer.
