Advance React Topics:
1. Lazy loading:
Code Splitting: Implement code splitting to split your bundle into smaller chunks that can be loaded on demand. This reduces the initial load time of your application.
React.lazy() and Suspense: Use React.lazy() along with Suspense to lazily load components. This allows you to load components asynchronously when they are needed, improving performance.
Route-based Lazy Loading: Implement lazy loading on routes to load only the necessary components for each route, rather than loading all components upfront.
Dynamic Imports: Utilize dynamic imports (import()) to dynamically load modules or components when certain conditions are met, enabling more fine-grained control over lazy loading.
2. Higher-Order Components:
Composition: Learn how to compose HOCs to add multiple behaviors to a component. This allows for better code reuse and separation of concerns.
Props Manipulation: Use HOCs to manipulate props passed to components, such as adding additional props or transforming existing ones.
Cross-cutting Concerns: Use HOCs to encapsulate cross-cutting concerns like authentication, logging, or performance monitoring, allowing you to apply these concerns to multiple components.
Render Props vs. HOCs: Understand the differences between HOCs and render props patterns and when to use each. Render props can provide more flexibility in some cases, while HOCs offer a simpler API.
3. Optimizaiton:
Memoization: Memoize expensive computations or function calls using techniques like useMemo() hook or libraries like memorize-one. This prevents unnecessary re-renders and improves performance.
Virtualization: Implement virtualization techniques such as windowing or infinite scrolling to efficiently render large lists or tables without impacting performance.
Server-Side Rendering: Consider SSR to improve the initial load time and SEO of your application by rendering the initial HTML on the server and hydrating it on the client.
Tree Shaking: Utilize tree shaking to remove unused code from your bundle during the build process, reducing the bundle size and improving loading times.
