        trim: PropTypes.bool
    };

    static defaultProps = {
        trim: true
    };

    componentDidMount() {
        let el = ReactDOM.findDOMNode(this);
        ReactDOM.unmountComponentAtNode(el);
        el.outerHTML = this.createComment();
    }

    createComment() {
        let text = this.props.text;

        if (this.props.trim) {
