概述
译注：本文需要 React.JS 和 ECMAScript 6作为基础知识，如果你还了解 Immutable.js 就更好了
Draft.js is a framework for building rich text editors in React, powered by an immutable model and abstracting over cross-browser differences.
Draft.js 是一个用来构建 React 富文本编辑器的框架，支持 Immutable 模型和跨浏览器兼容性。
Draft.js makes it easy to build any type of rich text input, whether you're just looking to support a few inline text styles or building a complex text editor for composing long-form articles.
Draft.js 很容易构建任何类型的富文本输入框，无论你只是想支持一些行内文本样式还是构建一个复杂的、创作长篇文章的文本编辑器。
Draft.js was introduced at React.js Conf in February 2016.

import {Editor, EditorState} from 'draft-js';
class MyEditor extends React.Component {
constructor(props) {
super(props);
this.state = {editorState: EditorState.createEmpty()};
this.onChange = (editorState) => this.setState({editorState});
}
render() {
return (
<Editor editorState={this.state.editorState} onChange={this.onChange} />
);
}

ReactDOM.render(
<MyEditor />,
document.getElementById('container')

Because Draft.js supports unicode, you must have the following meta tag in the
<head></head>block of your HTML file:
因为 Draft.js 支持 Unicode ，你必须在你的 HTML 文件的<head></head>区块中使用以下 meta 标签：
<meta charset="utf-8" />
Next, let's go into the basics of the API and learn what else you can do with Draft.js.
