title: How can I export dependency function and use a specific function?
body: <p>I want to export function <code>c</code> and use it in app.js but I think It would occur dependency error because If I import <code>c</code> and use it, func <code>c</code> calls <code>a, b</code> but file can't find func a and b. how can I implement this? Here's a example code what I was trying to do.</p>
  
  <pre><code>function a(){}
  function b(){}
  function c(){ a(); b();}
  export default c
  </code></pre>
