title: Best way to remove a "column" from a collection using Lodash?
body: <p>I'd like to remove one or more "columns" from a collection (array of objects) in JavaScript using Lodash.</p>
  
  <p>For example, in the following collection:</p>
  
  <pre><code>var users = [
    { 'name': 'barney', 'age': 36, 'alum': true },
    { 'name': 'fred',   'age': 40, 'alum': false }
  ];
  </code></pre>
  
  <p>...I may want to remove all columns that start with the letter A, or something similar.</p>
  
  <p>I know that I can achieve something similar on a per-object basis using the <code>_.omit()</code> method, but this does not seem to stick if I do it in an <code>each</code> loop.</p>
  
  <p>What is the best way to go about this using Lodash?</p>
