Some of the non-react libraries I'm using perform some DOM generation with javascript. Ideally, I'd like this to occur in react's render cycle but react doesn't implement some DOM functions.
ie. one library wants to create a fragment for showing a title (using jQuery) which in turn ends up calling document.createDocumentFragment.
A simple work around is to have the library do it's rendering on component mount or update. But I'm trying to render using the virtual DOM. Is there a better approach to re-creating or porting the library?

Before React 16.2, you could render only a single DOM node inside the render method. Now you can render multiple DOM nodes. In order to do this, wrap it inside a parent div which essentially makes it a single DOM node with multiple elements inside it. Fragments in React do not deviate much from their literal meaning.
Third-party libraries can be integrated with class components, also with functional components using Hooks. According to Dan Abramov, they (React Team in Facebook) have no plans to remove ES6 class syntax support in the future.
React uses virtual DOM to enhance its performance. It uses the observable to detect state and prop changes. React uses an efficient diff algorithm to compare the versions of virtual DOM. It then makes sure that batched updates are sent to the real DOM for repainting or re-rendering of the UI.
React can be used in any web application. It can be embedded in other applications and, with a little care, other applications can be embedded in React.
You need a "Portal". Take a look at https://github.com/ryanflorence/react-training/blob/gh-pages/lessons/05-wrapping-dom-libs.md This explains the solution very well, like so:
