what is react-developer-roadmap fr?

This is a visual learning roadmap for anyone who wants to become a React developer. React is a popular JavaScript library for building web application interfaces, and the learning path to mastering it involves many interconnected tools and concepts, this roadmap maps out a clear progression so you know what to learn and in what order. The roadmap starts with web fundamentals (HTML, CSS, JavaScript basics), then moves into React itself, and then branches out into the surrounding ecosystem: package managers like npm and yarn, styling tools like Sass and CSS frameworks, state management libraries like Redux and MobX, testing frameworks like Jest, and advanced topics like server-side rendering with Next.js, static site generation with Gatsby, and mobile apps with React Native. You would use this when you're new to React development and feeling overwhelmed by all the different tools and libraries people talk about. Instead of chasing whatever's currently trendy, it helps you understand the logical sequence of skills to build. It's a reference chart (provided as an image), not a tutorial, think of it as a map you consult when deciding what to study next. The project is JavaScript-based and the roadmap itself was built using Draw.io.
