<p><a href="https://reactjs.org/blog/2022/03/29/react-v18.html" target="_blank" rel="nofollow noopener noreferrer">React 18</a><span> </span>was years in the making, and with it brought valuable lessons for the React team. Its release was the result of many years of research and exploring many paths. Some of those paths were successful; many more were dead-ends that led to new insights. One lesson we’ve learned is that it’s frustrating for the community to wait for new features without having insight into these paths that we’re exploring.</p> <p>We typically have a number of projects being worked on at any time, ranging from the more experimental to the clearly defined. Looking ahead, we’d like to start regularly sharing more about what we’ve been working on with the community across these projects.</p> <p>To set expectations, this is not a roadmap with clear timelines. Many of these projects are under active research and are difficult to put concrete ship dates on. They may possibly never even ship in their current iteration depending on what we learn. Instead, we want to share with you the problem spaces we’re actively thinking about, and what we’ve learned so far.</p>

In this post, we’ll give an overview of what’s new in React 18, and what it means for the future.</p> <p>Our latest major version includes out-of-the-box improvements like automatic batching, new APIs like startTransition, and streaming server-side rendering with support for Suspense.</p> <p>Many of the features in React 18 are built on top of our new concurrent renderer, a behind-the-scenes change that unlocks powerful new capabilities. Concurrent React is opt-in — it’s only enabled when you use a concurrent feature — but we think it will have a big impact on the way people build applications.</p> <p>We’ve spent years researching and developing support for concurrency in React, and we’ve taken extra care to provide a gradual adoption path for existing users. Last summer,<span> </span><a href="https://reactjs.org/blog/2021/06/08/the-plan-for-react-18.html" target="_blank" rel="nofollow noopener noreferrer">we formed the React 18 Working Group</a><span> </span>to gather feedback from experts in the community and ensure a smooth upgrade experience for the entire React ecosystem.</p>
