title: TypeScript import from
body: <p>All:</p>
  
  <p>When I read "Angular2 5mins start"-Tutorial, the first syntax confuses me:</p>
  
  <pre><code>import {bootstrap, Component} from 'angular2/angular2';
  </code></pre>
  
  <p>I wonder where can I find this syntax from TypeScript (I only find import, but not import...from)?</p>
  
  <p>Thanks</p>
