Initial State

👨‍💼 Hello! So here's where we're starting out:

import { createRoot } from 'react-dom/client'

function Counter() {
	const [count, setCount] = useState(0)
	const increment = () => setCount(count + 1)

	return (
		<div className="counter">
			<button onClick={increment}>{count}</button>
		</div>
	)
}

const rootEl = document.createElement('div')
document.body.append(rootEl)
const appRoot = createRoot(rootEl)
appRoot.render(<Counter />)

Pretty simple, except the useState function isn't defined and we're not allowed to simply import it from React because we're not allowed to directly use any React hooks in this workshop!

And because it's not defined, our Counter component won't be able to render anything (because an error will be thrown).

So let's just get it to the point where the Counter component renders initially without errors. When you're done, it should render a button with a 0 in it.

The emoji should lead the way!
