In this first chapter, we have learned some basic concepts that are very important for following the rest of the book, and that are crucial to working with React daily. We now know how to write declarative code, and we have a clear understanding of the difference between the components we create and the elements that React uses to display their instances on the screen.
We learned the reasons behind the choice of locating logic and templates together, and why that unpopular decision has been a big win for React. We went through the reasons why it is common to feel fatigued in the JavaScript ecosystem, but we have also seen how to avoid those problems by following an iterative approach.
We learned how to use TypeScript to create some basic types and interfaces. Finally, we have seen what the new create-react-app CLI is, and we are now ready to start writing some real code.
In the next chapter, you will learn how to use JSX/TSX code and apply very useful configurations to improve your code style.
