React.render replace container instead of inserting into

Question

I\'m gradually replacing some Backbone views with React.

My React View:

Rendered By React

Answer 1

This appears to work:

const linkEl = ;
const linkElAsDirectChildOfHead = ReactDOM.createPortal(linkEl, document.head); // portal will do actual adding-to-head
ReactDOM.render(linkElAsDirectChildOfHead, document.createElement("div")); // render stub into never-added container

The result:

Note that, as desired, it doesn't delete the other children within document.head.

Not sure if this method has any negative side-effects, but at first glance it appears to work.
