But why even bring up the topic of virtual DOM in a course addressed at beginners? If you picture your target audience as so new to the field, why should they even care how React is working under the hood to change the contents of the screen?

Virtual DOM (unless I am mistaken) is a solution to the problem that React would have otherwise introduced. But surely, selling points of a framework are not how it solves its own technical problems, but rather what problems it undertakes to solve for its user.
