title: reduce javascript code when using the map function
body: <p>I want to iterate over an array and do something to each of the element</p>
  
  <pre><code>d = d.map(function(d){
      return _.omit(d, 'password');
  })
  
  d = d.map(function(d){
      return d.toString();
  })
  </code></pre>
  
  <p>these functions are working correctly.  But after it showed up too many times the code becomes really messy. </p>
  
  <p>So I was wondering if there's easier ways to do what I want to do? I am hoping to reduce the code to one line only using bind or apply keywords or some modules (maybe lodash or underscore..).  Is this possible?   </p>
