Among all other JavaScript libraries, React.js stands out. It relies on reusable components, not templates, for UI development, allowing developers to render views where data changes over time. React applications are more scalable and more maintainable, making developers more efficient and users more satisfied. In this course, our mentor introduces the basics of the React library using the most modern syntax and best practices for creating React components. Along the way, learn how to set up Chrome tools for React; create new components; use props and state to pass data between components; and more. By the end of the course, you’ll understand the essentials of React.js and be able to start building your own browser-based projects.
