GK840204 REACT Foundations

COURSE OBJECTIVE:
• Set up a React development environment and create an initial application structure. • Construct JSX elements to build React component structures and handle dynamic content. • Build reusable React components applying composition patterns. • Implement prop patterns to pass data and event handlers between components. • Use state hooks to manage component data and handle user interactions. • Integrate data flow patterns to manage component communication and state sharing. • Implement container and presentational component patterns to organize React applications effectively. • Apply styling using CSS modules and styling organization patterns. • Use the useEffect hook to manage side effects and component lifecycle needs. • Build form interfaces using both controlled and uncontrolled form patterns. • Use React Developer Tools to debug component issues and analyze application performance.

TARGET AUDIENCE:
– Front-End Developers- Web Developers- Software Engineers- Technical professionals

COURSE PREREQUISITES:
This is an intermediate level course for those looking to expand their skill set and master REACT. Learners should have proficiency in JavaScript, HTML, and CSS.
