title: Use method define in node.js module exports
body: <p>I have a node.js module that has <code>foo</code> and <code>bar</code>. Is there a way for me to call <code>foo</code> inside of <code>bar</code> like:</p>
  
  <pre><code>module.exports = {
      foo: function(a, b, c) {
  
      },
  
      bar: function(a, b, c) {
          foo(); //returns 'foo is not defined'
      }
  }
  </code></pre>
  
  <p>As is, <code>foo</code> returns undefined... can someone help?</p>
  
  <p>Thanks in advance!</p>
