## en-US

Comment can be used as an editor, so the user can customize the contents of the component.

```tsx
import { Avatar, Button, Comment, Form, Input, List } from 'antd';
import moment from 'moment';
import React, { useState } from 'react';

const { TextArea } = Input;

interface CommentItem {
  author: string;
  avatar: string;
  content: React.ReactNode;
  datetime: string;
}

interface EditorProps {
  onChange: (e: React.ChangeEvent<HTMLTextAreaElement>) => void;
  onSubmit: () => void;
  submitting: boolean;
  value: string;
}

const CommentList = ({ comments }: { comments: CommentItem[] }) => (
  <List
    dataSource={comments}
    header={`${comments.length} ${comments.length > 1 ? 'replies' : 'reply'}`}
    itemLayout="horizontal"
    renderItem={props => <Comment {...props} />}
  />
);

const Editor = ({ onChange, onSubmit, submitting, value }: EditorProps) => (
  <>
    <Form.Item>
      <TextArea rows={4} onChange={onChange} value={value} />
    </Form.Item>
    <Form.Item>
      <Button htmlType="submit" loading={submitting} onClick={onSubmit} type="primary">
        Add Comment
      </Button>
    </Form.Item>
  </>
);

const App: React.FC = () => {
  const [comments, setComments] = useState<CommentItem[]>([]);
  const [submitting, setSubmitting] = useState(false);
  const [value, setValue] = useState('');

  const handleSubmit = () => {
    if (!value) return;

    setSubmitting(true);

    setTimeout(() => {
      setSubmitting(false);
      setValue('');
      setComments([
        ...comments,
        {
          author: 'Han Solo',
          avatar: 'https://joeschmoe.io/api/v1/random',
          content: <p>{value}</p>,
          datetime: moment('2016-11-22').fromNow(),
        },
      ]);
    }, 1000);
  };

  const handleChange = (e: React.ChangeEvent<HTMLTextAreaElement>) => {
    setValue(e.target.value);
  };

  return (
    <>
      {comments.length > 0 && <CommentList comments={comments} />}
      <Comment
        avatar={<Avatar src="https://joeschmoe.io/api/v1/random" alt="Han Solo" />}
        content={
          <Editor
            onChange={handleChange}
            onSubmit={handleSubmit}
            submitting={submitting}
            value={value}
          />
        }
      />
    </>
  );
};

export default App;
```
