React Essential Guide

This guide combines theory and practice through the development of progressive mini-projects where we implement the essential concepts of React: functional components, state management, props, hooks, and JSX. Each module includes:

• Detailed technical explanations in written format
• Step-by-step video tutorials
• Practical exercises with commented solutions
• Supplementary material based on the official documentation

It is important to note that this guide is directly derived from the official React.js documentation (https://react.dev/learn). The work done here involved translation, expanding the concepts for greater clarity, adding new features and processes such as deployment, and implementing code improvements. By the end, you will have a solid understanding of the JavaScript library for rendering user interfaces (UI), and you’ll be familiar with the upcoming changes in React 19.
