What’s new in the world of React? | React Conf 2024 Recap
React Conf 2024 just wrapped up, and it was filled with exciting announcements and updates on the popular JavaScript library. Here’s a recap of some of the most important highlights from the event:
New Features
One of the biggest announcements at React Conf 2024 was the introduction of a new feature called React Hooks. Hooks are a new way to use state and other React features without writing a class. This simplifies the code and makes it easier to understand and maintain. Developers can now use hooks like useState and useEffect to manage state and side effects in functional components.
Improved Performance
React 18 was also announced at the conference, with a focus on improving performance and enhancing the developer experience. The new version includes features like automatic batching of updates, concurrent rendering, and suspense for data fetching. These improvements will make React apps faster and more responsive, especially for complex applications.
Tooling Updates
React developers will also benefit from updates to the tooling ecosystem. The new React DevTools extension provides enhanced debugging capabilities, including improved support for concurrent mode and hooks. Additionally, tools like Create React App have been updated to support the latest features and best practices.
Community Engagement
React Conf 2024 highlighted the importance of community engagement and collaboration. The React team encouraged developers to contribute to the open-source project, participate in forums and events, and share their knowledge with others. By working together, the React community can continue to innovate and grow.
Conclusion
React Conf 2024 was a success, showcasing the latest advancements in the world of React. With new features like React Hooks, improved performance in React 18, updates to tooling, and a focus on community engagement, developers have plenty to be excited about. The future of React looks bright, and we can’t wait to see what the community builds next!

CJ you’re awesome, your videos are the best 👍
thnx CJ
I'm excited about CJ😊
Signals are too complicated?! People hate React because of how leaky and convoluted the abstractions are… now they want to say people can't manage their own state or reactivity with signals… because they would rather build more leaky abstractions instead. When will React team learn their lesson 😂
Always love for CJ – ♥
This format is great, monthly round up format? 🤔
I feel like React is going to be a cult
When they mention that their approach is what made React approachable (in the Signals section), I think they are overlooking that the only approachable thing about React is JSX, all the rest is a weird mental model
Great video
Wanted to come but was too busy building my own JavaScript framework
cj this is some good content
Thanks for summarizing! 👍🏻
