I love the components part, my personal webiste is in Next.js but I really struggle to understand the "state mental model" and I guess thats what puts me off :)

Even from tutorial perspective, people tend to explain react like here is useState and if you do this, you can now update other parts. But I am a newbie so I guess its either sucking up and spending more time with it or just struggling with trying to solve the same things with more code in vanilla ¯\_(ツ)_/¯
