title: How to show html entity using React?
body: <p>I am wanting to show the 'cubic' html entity (superscript 3). I am doing like 
   this:</p>
  
  <pre><code>const formatArea = function(val){
      return val + " ft&amp;sup3;";
  }
  </code></pre>
  
  <p>where <code>formatArea</code> is being called from inside the component':</p>
  
  <pre><code>render(){
      return (
          &lt;div&gt;
              {formatArea(this.props.area)}
          &lt;/div&gt;
      );
  }
  </code></pre>
  
  <p>but, the browser is showing it as <code>ft&amp;sup3;</code></p>
