REACT Foundations

React Foundation offers a thorough introduction to React, a widely-used JavaScript library for building user interfaces. This course covers essential and advanced topics, including component-based architecture, state management with hooks, and styling techniques. Participants will learn to set up a React development environment, create reusable components, manage data flow, and handle side effects with the useEffect hook.

By the end of the course, you will learn to construct JSX elements, implement prop patterns, manage state, and debug React applications effectively. You will be equipped to build high-performance, scalable, and maintainable web applications.

This course includes hands-on practice through labs and exercises, reinforcing the concepts covered in the lectures - a balanced mix of theoretical knowledge and practical application, ensuring a comprehensive learning experience.
