In this video on "React 18 Overview" we are going to discuss about React 18 new features and changes, improvements done on react 18 and new hooks that has being added to React 18 and many more. This React 18 Tutorial will help you understand new features that we will talk about in this video. We will also talk about Automatic Batching, Better Rendering, and about the Strict Mood in this video. At last, We will see the Changes done on React 18 in terms of Client Side API, Server Side API and Library Side. In this video you will learn - 00:00 React 18 Overview 01:32 React 18 New Features and Changes 01:50 New Improvement done in React 18 02:33 What's new in React 18? 08:22 New Hooks 08:42 Strict Mood 09:18 Changes Done in React 18 Automatic batching in React 18 All state modifications made using event handlers are grouped together using React's built-in batching functionality. It prevents the files from going through a pointless rendering procedure. React 18 also features a modified version of batching called React 18 Automatic Batching that groups all state modifications made by create Root together. The process uses timeout and interval functions, asynchronous applications, event handlers, and batch state changes; the background of the updates is not required. So automatic batching is nothing but to do all the microtask together at the end of the task to save time. Transition in React 18 A transition is a new concept in React to distinguish between urgent and non-urgent updates •Urgent updates reflect direct interaction, like typing, clicking, pressing, etc. •Transition updates transition the UI from one view to another. So let me give you an example if you doing a task and another urgent task comes in that has a higher priority so, react will stop that task and work on the higher priority task and then start that task again. Suspense in React 18 React suspense is a feature that enables developers to monitor the rendering elements while the process is still in progress. It then displays its fallback functionality. This functionality can be used in conjunction with the transition API with the most recent React version. It even pauses the rendering schedule to lessen the effect of loading by preventing the content from being changed. The react suspense is quite helpful since it provides a calm loading state while the user is dealing with a network conflict. 🔥Explore Free Course to Learn React JS Basics With Completion Certificate by SkillUp: https://www.simplilearn.com/learn-rea... ✅Subscribe to our Channel to learn more about the top Technologies: https://bit.ly/2VT4WtH #React18 #ReactUpdates #ReactJS #ReactTutorialForBeginners #ReactTutorial #ReactJSTutorial #ReactHooks #2022 #2023 #Programming #Simplilearn ⏩ Check out more React JS Tutorial videos: • ReactJS Tutorial ... 🔥 Watch Top Trending Videos From Simplilearn: ⏩Top 10 Programming Languages in 2023: • Top 10 Programmin... ⏩Top 10 Certificatio
