Nesting demo in plain JavaScript

[michaelborromeo]

How would you create the nesting demo but in plain JavaScript, not React?

Thanks!

A sub-button is inside the root button tippy's content. You call tippy() on the sub-button too, ad infinitum for further nesting

tippy(rootButton, {
  content: elementContainingSubButton,
});

tippy(subButton, {
  content: 'nested'
});
