Do I need to build my projects without a framework/library to understand more?

Hi. Tech newbie here, although I've had an account here for some time.

I've been having struggles starting my projects and sticking to it till I finish, especially when I try to use frameworks like React. Working with state in React is one thing I still struggle with. When a library like Redux comes in, I get a lot more caught up with mastering the framework/library before I start my project.

Since I didn't have much experience making projects without a framework,(e.g did not work with DOM much before React either, I only had a few projects using a basic HTML/CSS/JS file), do I need to focus on projects without a framework to help with my understanding of React and/or any other framework/library?
