LAZY E SUSPENSE | REACT.JS PT-26

React.js is a popular JavaScript library for building user interfaces. With the introduction of React 16.6, a new feature called Lazy and Suspense was added, allowing developers to easily improve the performance of their web applications.

Lazy Loading Components

Lazy loading is a technique that allows components to be loaded only when they are needed. This can greatly improve the initial load time of a web page, as only the essential components are loaded first, and the rest are loaded as the user interacts with the application.

Suspense for Data Fetching

Suspense is another new feature in React 16.6 that allows developers to handle data fetching in a more elegant way. With Suspense, developers can specify loading indicators for components that need to fetch data, and easily handle any errors that may occur during the data fetching process.

Implementation in React.js

To implement Lazy and Suspense in React.js, developers can use the new “lazy” and “Suspense” components, which are introduced in React 16.6. These components make it easy to lazy load components and handle data fetching with suspense, improving the overall performance and user experience of the application.

Conclusion

Lazy and Suspense are powerful new features in React 16.6 that can greatly improve the performance and user experience of web applications. With lazy loading and suspense for data fetching, developers can easily optimize their applications and provide a smoother experience for their users.
