Looking to learn and build a react app, should I start with this? Did review some html css prior.
If you want to learn, my advice would be to focus on learning one thing at a time. Pick up react. Just react. NextJS (and other libraries included here) solve specific problems in specific ways. It's hard to know if they solve them in the way that works for you if you don't understand the problem they are solving, or what other approaches might look like. Once you're comfortable with how react works, then start layer…
One of the best things about Next is that it configures everything for you and lets you just start writing some React code and seeing results. I would recommend the GP start with Next, and dig deeper as they go along
