It introduces automatic memoization, eliminates the need for 'useCallback' and 'memo', and replaces 'React.lazy' with react server components. The 'useContext' hook will also undergo changes, and server actions will be more stable. ## Content React 19 is an upcoming major release that is creating a lot of buzz in the React community. With the introduction of a new compiler, React is set to become more performant and easier to work with. Gone are the days of manual memoization, as React 19 brings automatic memoization, eliminating the need for 'useCallback' and 'memo' in our code. This major change will have a significant impact on how we teach and learn React. One of the most anticipated features in React 19 is the new compiler. Although it is not yet released, it shows great promise in simplifying memoization in React. By memoizing all hooks, props, and components, unnecessary re-renders will be eliminated. This will reduce the reliance on 'useMemo' and 'useCallback', making our code more efficient and performant. Additionally, React 19 will introduce other exciting improvements. The 'React.lazy' function will be replaced with react server components, allowing for more efficient loading of components. The 'useContext' hook will also undergo changes, further enhancing developer experience. Another notable feature in React 19 is the stable state of server actions. This means that data submission can now be done synchronously or asynchronously, providing developers with more flexibility and control. With all these changes and improvements, React 19 is set to revolutionize the way we build applications with React. Stay tuned for its release and get ready to level up your React skills! ## Community discussion Top comments from developers on daily.dev. **@natheeshkumar** · 2 upvotes > Any expected date for release? **@bibash1122** · 0 upvotes > React 19 beta version is out **@kazimkayhan** · 0 upvotes > This collection covers main features of React19 **@devnet101kent** · 0 upvotes > Exciting... will have to dig into this. ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments - [CNCF Unveils Schedule for KubeCon \+ CloudNativeCon Europe 2026](https://daily.dev/posts/cncf-unveils-schedule-for-kubecon-cloudnativecon-europe-2026-ikhcoa5cb) · CNCF · 2 upvotes · 0 comments - [CNCF Debuts KubeCon \+ CloudNativeCon Japan 2026 Schedule](https://daily.dev/posts/cncf-debuts-kubecon-cloudnativecon-japan-2026-schedule-xp5pyudub) · CNCF · 1 upvotes · 0 comments --- Tags: [#compiler](https://daily.dev/tags/compiler), [#performance](https://daily.dev/tags/performance), [#react](https://daily.dev/tags/react) [View this post on daily.dev](https://daily.dev/posts/what-to-expect-in-react-19-a-major-release-with-exciting-improvements-acaaijhbx) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"What to Expect in React 19: A Major Release with Exciting Improvements","url":"https://daily.dev/posts/what-to-expect-in-react-19-a-major-release-with-exciting-improvements-acaaijhbx","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/what-to-expect-in-react-19-a-major-release-with-exciting-improvements-acaaijhbx"},"datePublished":"2024-03-12T15:28:02.499Z","dateModified":"2025-12-08T02:17:27.223Z","description":"React 19 is an upcoming major release with exciting improvements such as a new compiler for better performance and easier work.
