 `Editable` is an extensible rich text editor framework that focuses on stability, controllability, and performance. To achieve this, we did not use the native editable attribute [~~contenteditable~~](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/contenteditable), but instead used a custom renderer that allows us to better control the editor's behavior. From now on, you no longer have to worry about cross-platform and browser compatibility issues (such as `Selection`, `Input`), just focus on your business logic.

 Editable 是一个可扩展的富文本编辑器框架，专注于稳定性、可控性和性能。为此，我们没有使用原生的可编辑属性[~~contenteditable~~](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/contenteditable)，而是使用了一个自定义的渲染器，这使得我们可以更好地控制编辑器的行为。从此，您不必再担心跨平台和浏览器兼容性问题（例如`Selection`、`Input`），只需专注于您的业务逻辑。
