Is it possible to pass context into a component instantiated with ReactDOM.render?

Question

TL;DR Given the following example code:

ReactDOM.render(, someDomNode);

Is it possible to manually pas

Answer 1

In React 15 and earlier you can use ReactDOM.unstable_renderSubtreeIntoContainer instead of ReactDOM.render. The first argument is the component who's context you want to propagate (generally this)

In React 16 and later there's the "Portal" API: https://reactjs.org/docs/portals.html
