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);

Commencez par la section « JSX Prevents Injection Attacks » liée dans l’issue et vérifiez les deux affirmations citées à la lumière du comportement de Text-node décrit. Ne mettez à jour la documentation que si la formulation est inexacte, et veillez à ce que l’explication révisée décrive correctement la manière dont les valeurs JSX sont rendues.
