React DOM escapes any values

I have discussed this particular sentence with a colleague:

By default, React DOM escapes any values embedded in JSX before rendering them. Thus it ensures that you can never inject anything that’s not explicitly written in your application. Everything is converted to a string before being rendered.

https://reactjs.org/docs/introducing-jsx.html#jsx-prevents-injection-attacks

Specific these two quotes: "React DOM escapes any values embedded in JSX before rendering them" and "Everything is converted to a string before being rendered"

As far as we know, everything is assigned via a Text-node and not escaped as the first sentence describes.

Mimicked example

const test = `<script>console.log("My log")</script>`;
let body = document.querySelector('body');
let content = new Text(test);
body.appendChild(content);

Beginne mit dem im Issue verlinkten Abschnitt „JSX Prevents Injection Attacks“ und überprüfe die beiden zitierten Aussagen anhand des beschriebenen Verhaltens von Text-node. Aktualisiere die Dokumentation nur, wenn die Formulierung ungenau ist, und stelle sicher, dass die überarbeitete Erklärung korrekt beschreibt, wie JSX-Werte gerendert werden.
