title: Property 'values' does not exist on type 'ObjectConstructor'
body: <p>In the following I am converting an enum in to an array, it seems that I may have something missing in my tsconfig.json.</p>
  
  <p>This is the script:</p>
  
  <pre><code>const menuItems = Object.values(MediaListFilterType).map(value =&gt; ({
      type: value,
      description: () =&gt; {
          switch (value) {
              case value === MediaListFilterType.notPitched:
                  return 'Exclude already pitched';
                  break;
              case value === MediaListFilterType.notDoublePitched:
                  return 'Exclude double pitched';
                  break;
              case value === MediaListFilterType.assignedToMe:
                  return 'Assigned to me';
                  break;
              case value === MediaListFilterType.notAssigned:
                  return 'Unassigned';
                  break;
          }
      }
  }));
  </code></pre>
  
  <p>this gives me this error:
  <code>Property 'values' does not exist on type 'ObjectConstructor'.</code></p>
  
  <p>and the tsconfig is as follows...</p>
  
  <pre><code>{
    "compilerOptions": {
      "module": "es6",
      "target": "es2015",
      "sourceMap": true,
      "jsx": "react",
      "moduleResolution": "node",
      "declaration": false,
      "allowSyntheticDefaultImports": true
    }
  }
  </code></pre>
  
  <p>I am a bit new at this so I am not sure what I need to change in the tsconfig. Help!</p>
