We can pass all the reset properties of mark to the element.

if (markPointIsObject) {
  const { label, style, ...resetProps } = markPoint;
}

<span {...resetProps>{label}</span>

There you go 😃 I hope I got your idea

[yesmeck]

I mean we can write mark prop on the config object directly.

const marks = [{
 label: '85°C',
 id: 'custom-id',
}];

if (markPointIsObject) {
  const { label, style, ...resetProps } = markPoint;
}

<span {...resetProps>{label}</span>
