The update to the React core algorithm has been years in the making — it offers a ground-up rewrite for how React manages reconciliation. React will maintain the same public API and should allow for immediate upgrade for most projects (assuming you’ve fixed the deprecation warnings). The main goals of the release are the following:
- Ability to split interruptible work in chunks.
- Ability to prioritize, rebase and reuse work in progress.
- Ability to yield back and forth between parents and children to support layout in React.
- Ability to return multiple elements from
render(). - Portals
- Better support for error boundaries.
