title: TypeScript enum to specific object
body: <p>I have the following TypeScript enum:</p>
  
  <pre><code>export declare enum SupportedLanguages {
      en,
      fr
  }
  </code></pre>
  
  <p>If I import it in my react application and <code>console.log</code> it, I will get the following object returned:</p>
  
  <pre><code>{
    en: "en", 
    fr: "fr"
  }
  </code></pre>
  
  <p>How can I manipulate it, so that I get the following object returned?</p>
  
  <pre><code>{
    en: "",
    fr: ""
  }
  </code></pre>
  
  <p>I tried it with <code>const Lang = Object.keys(SupportedLanguages)</code> and also with <code>.map()</code> but I did not get the expected object returned.</p>
