Times a synchronous workload and reports the elapsed milliseconds.

import { render } from 'pota'
import { timing } from 'pota/use/time'

function heavyWork() {
	let sum = 0
	for (let i = 0; i < 1e6; i++) sum += i
	return sum
}

function App() {
	const ms = timing(heavyWork)
	return <p>took {ms.toFixed(2)}ms</p>
}

render(App)
