Here is a simple stopwatch, adapted from VanJS doc.
As you can see, nothing complicated, plain JS, no hooks, no bundling, all this under 1.2kB of library !!!
const {button,span, div, pre, h1} = van.tags const elapsed = van.state("0.00") const Stopwatch = () => { let id; const start = () => id = id || setInterval(() => elapsed.val = (Number(elapsed.val) + 0.01).toFixed(2), 10) return span( button({onclick: start}, "Start"), button({onclick: () => (clearInterval(id), id = 0)}, "Stop"), button({onclick: () => (clearInterval(id), id = 0, elapsed.val = "0.00")}, "Reset"), ) } const Screendisplay = () => h1(elapsed, " s") van.add(app, div( h1("A Simple Stopwatch"), div ({class:"stopwatch"}, div({class:"content"}, Screendisplay(), Stopwatch()) ) ) )

Thanks for sharing the example. Have you considered adding this example to your VanJS series: dev.to/artydev/series/23075?
Done :-)
Thank you Tao
