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);

Comece pela seção „JSX Prevents Injection Attacks“ vinculada na issue e verifique as duas afirmações citadas com base no comportamento descrito de Text-node. Atualize a documentação somente se a redação estiver incorreta e certifique-se de que a explicação revisada descreva com precisão como os valores JSX são renderizados.
