reflection to pass tagName as string props to be rendered

class Button  extends React.Component{
    renderAnchor(){
      return <a onClick={this.props.onClick}>{this.props.children}</a>
    }
    renderButton(){
       return <button onClick={this.props.onClick}>{this.props.children}</button> 
    }
    render(){
         return (this.tagName==='a')?this.renderAnchor():this.renderButton();
    }

}

I have the above react-component , i want to avoid code redundancy, so , i decide to remove all render methods except the last (render) by replacing the tagname by this.props.tagName

     render(){
         return <{this.props.tagName} onClick={this.props.onClick}>{this.props.children}</{this.props.tagName}>
    }

However, it raises an error of syntax .

How can use reflection of tagname in react / ES7/ Babel ?
