title: Global variables for node.js standard modules?
body: <p>I know that global variables are bad.</p>
  
  <p>But if I am using node's module "util" in 40 files in my framework, isn't it better to just declare it as a global variable like:</p>
  
  <pre><code>util = require('util');
  </code></pre>
  
  <p>in the index.js file instead of writing that line in 40 files?</p>
  
  <p>Cause I often use the same 5-10 modules in each file, that would save a lot of time instead of copy paste all the time.</p>
  
  <p>Isn't DRY good in this case?</p>
