To make React.startTransition more consistent with the hook form of startTransition, we capture errors thrown by the scope function and pass them to the global reportError function. (This is also what we do as a default for onRecoverableError.) This is a breaking change because it means that errors inside of startTransition will no longer bubble up to the caller. You can still catch the error by putting a try/catch block inside of the scope function itself. We do the same for async actions to prevent "unhandled promise rejection" warnings. The motivation is to avoid a refactor hazard when changing from a sync to an async action, or from useTransition to startTransition.
react
React is a JavaScript library for creating user interfaces.
The react package contains only the functionality necessary to define React components. It is typically used together with a React renderer like react-dom for the web, or react-native for the native environments.
Note: by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages. Don't forget to use the production build when deploying your application.
Usage
import { useState } from 'react';
import { createRoot } from 'react-dom/client';
function Counter() {
const [count, setCount] = useState(0);
return (
<>
<h1>{count}</h1>
<button onClick={() => setCount(count + 1)}>
Increment
</button>
</>
);
}
const root = createRoot(document.getElementById('root'));
root.render(<Counter />);
