title: Why are the TypeScript compilerOptions 'noEmitOnError: true' and 'isolatedModules: false' not compatible?
body: <p>When I run TypeScript with <code>isolatedModules</code> true and <code>isolatedModules</code> false, I get this error: </p>
  
  <pre><code>tsconfig.json(5,9): error TS5053: Option 'noEmitOnError' cannot be specified with option 'isolatedModules'.
  </code></pre>
  
  <p>Why??</p>
  
  <p>Example tsconfig:</p>
  
  <pre><code>{
      "compilerOptions": {
          "noEmitOnError": true,
          "isolatedModules": true,
      }
  }
  </code></pre>
