First, my goal is to update it frequently. Then, I wrote a book about React (in French) three years ago, you’d be surprised to see how relevant it still is ;)
People are learning next.js from materials that will be irrelevant in months every day. Doesn’t mean we should discourage people from creating more materials.
This person not only covered the big release from a few days ago, but committed to keeping it up to date as the framework changes. Not sure what else we can ask for.
