 Thank you so much for taking this course on Essential React. We started with Hello World and JSX and getting a project started, covered events, state, state management with the object and functional form of set state, knowing and unknowing components in all of its various names, and made our way all the way to composition with component props, render props, and higher order components. From here, you should have a pretty good grasp of how React components work. I've covered all the essentials, but I'm sure you have a lot of questions left. Please check out some of the other courses. I'm always making more, and they should help clarify a few things for you. Thanks again.
