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);

Start with the JSX Prevents Injection Attacks section linked in the issue and verify the two quoted claims against the described Text-node behavior. Update the documentation only if the wording is inaccurate, and ensure the revised explanation accurately describes how JSX values are rendered.
