React 19: Looking into the Future
The React team is working on React 19 to improve performance and developer experience. Here are the highlights.
React Compiler (React Forget)
You might not need useMemo and useCallback anymore. The compiler automatically optimizes unnecessary renders.
javascript
// Before
const filteredList = useMemo(() => list.filter(item => item.active), [list]);
// React 19 (With Compiler)
const filteredList = list.filter(item => item.active);
// Automatically memoized!Server Actions
Managing form submissions and data mutations has never been easier.
javascript
async function updateProfile(formData) {
'use server';
await db.user.update({ name: formData.get('name') });
}
