React.js is a powerful frontend library for building dynamic and fast web apps. Lazy loading and code splitting techniques are used for performance optimisation. React.lazy and Suspense components load dynamically, which reduces the initial load time. Avoid needless re-renders with Memoization and React.PureComponent. State management solutions, such as Redux and Context API, can increase performance and scalability for large systems. Virtual DOM rendering is efficient in reflecting changes. Event handling and hooks help to improve the app's responsiveness. CSS-in-JS and modular CSS help to increase maintainability. 

Testing frameworks, such as Jest and the React Testing Library, ensure that code is resilient and error free. Component reusability makes development faster and more consistent. Error boundaries prevent applications from crashing. SEO optimisation and server-side rendering can boost the visibility of React applications. It is necessary to follow code linting and best practices in order to have a maintainable code base. Continuous monitoring and performance audits make the app experience better.

Key takeaways:

• Lazy loading and code splitting help to increase performance.


• State management and component reusability are critical for large applications.


• Apps that test and handle errors are more resilient.
