Suspense SSR in React 18

React 18 will include architectural improvements to React server-side rendering (SSR) performance. These improvements are substantial and are the culmination of several years of work. Most of these improvements are happening behind the scenes, but there are some selective mechanisms you need to be aware of, especially if you don't

React functional component performance optimization

Reduce the number of rerenders. If shouldComponentUpdate() returns false, then the diff is stopped, so render is not executed to reduce performance overhead and computation. The main reason is to reduce double counting. For functional components, each re...

In the previous version, diff of the React virtual DOM did not interrupt, which took up a lot of execution time, resulting in delayed rendering and page stutter. The React team wanted to be able to perform small asynchronous tasks...
