const useCount = initialCount => {
	const [count, setCount] = useState(initialCount);

	return { onClick: () => setCount(count + 1), children: count };
};

const PairedCount = pair(useCount);

const Component = ({ array = [] }) => (
	<ul>
		{array.map(key => (
			<PairedCount key={key}>
				{usePairedCount => {
					const props = usePairedCount(key);

					return (
						<li>
							<button type="button" {...props} />
						</li>
					);
				}}
			</PairedCount>
		))}
	</ul>

	return { onClick: () => setCount(count + 1), children: count };
};

const PairedCount = pair(useCount);

const Component = ({ array = [] }) => (
	<ul>
		{array.map(key => (
			<PairedCount key={key}>
				{usePairedCount => {
					const props = usePairedCount(key);

					return (
						<li>
							<button type="button" {...props} />
						</li>
					);
				}}
			</PairedCount>
		))}
	</ul>
);

	const Component = ({ array = [] }) =>
		createElement("ul", {
			children: array.map(key =>
				createElement(PairedCount, {
					key,
					children: usePairedCount => {
