Sebastian Markbåge 0ac3ea471f Use getComponentNameFromType for debug info for the key warning (#27930)
If this is a client reference we shouldn't dot into it, which would
throw in the proxy.

Interestingly our client references don't really have a `name`
associated with them for debug information so a component type doesn't
show up in error logs even though it seems like it should.

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 />);
