React is a Javascript library that is used by most web development company in India. You can use react to make beautiful UI. React is managed by Facebook and they give some general updates for the product. This blog is about the new updates in React.

React 18 is finally here. You might have questions about what's new. Don't worry, because this article will cover some of the biggest changes of new release. Some really exciting improvements have been launched with the new version of React, and I'm excited to go over them with you!

React 18 comes with new features to improve performance. Previous versions were helping developers make apps much faster, but there were certain limitations along the way. In React 18, Facebook has removed some of these limitations and added new features for the same.

How To Install React 18

React is a javascript library that helps us to build and create front-end interfaces for Single page applications, it utilizes the power of virtual DOM. ReactJS gives us the ability to create reusable UI components which are also called reusable React components or just React components. 

To install react 18 Write the below line in your cmd

npm install react@alpha react-dom@alpha

Automatic Batching

In React 17, if you change the state of the component two times, the component will re-render two times. In React 18, the two updates will be batched, and the component will render only once. This will improve the overall performance of your application and reduce unnecessary load on the system. Still, if you want to render one by one then use flushSync.

Example:-

Start Transition

Another new React 18 feature includes Transition updates, which transition the UI from one view to another. Transitions are a new concept in React to distinguish between urgent and non-urgent updates. Urgent updates reflect direct interaction, like typing, pressing, and so on. Transitions update the UI over time as animation or movement that isn't user-initiated.

Example:-

Suspense

Suspense lets you declaratively specify the loading state for a part of the component tree if it’s not yet ready to be displayed. When used on its own, without React Loadable or other higher-level features like them, Suspense can be a solution when your application has a lot of data. It might also provide a signal to your pages that they should consider lazy-loading chunks of their content to provide faster load times

SSR and Issue

• Loading Some Data from Server Side But that time App not working.
• Because first load  Html and CSS then JS will load
• The suspense will show some default data or loader
