const charLimit = 140;
const [text, setText] = useState('');

useEffect(() => setText('Great job. This is excellent!'), []);

return (
  <TextArea
    label='Comment'
    maxlength={charLimit}
    value={text}
    onValueChanged={({ detail: { value } }) => setText(value)}
    helperText={`${text.length}/${charLimit}`}

Automatic height adjustment

Unless set to a fixed height, Text Area adjusts its height automatically based on its content. The default and minimum height is two rows of text.

Minimum and maximum height
