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);

从 issue 中链接的“JSX Prevents Injection Attacks”部分开始，并根据所描述的 Text-node 行为核实其中引用的两项说法。仅在措辞不准确时更新文档，并确保修订后的说明准确描述 JSX 值是如何渲染的。
