title: What's the difference between typescript.js and typescriptServices.js?
body: <p>TypeScript comes with 3 JavaScript compiled files in its 'bin' folder:</p>
  
  <ul>
  <li>tsc.js -- command-line-run compiler itself;</li>
  <li>typescript.js -- ??</li>
  <li>typescriptServices.js -- ??</li>
  </ul>
  
  <p>I guess one of those should be 'TypeScript language service', but what's the other one?</p>
