title: lodash; replace and merge two arrays of strings
body: <p>Is there any function in <a href="https://lodash.com/docs" rel="nofollow">lodash</a> to merge two arrays something like;</p>
  
  <pre><code>var arr_1 = ['1', '0', '1'], arr_2 = ['0', '1', '1'];
  </code></pre>
  
  <p>Result should return:</p>
  
  <pre><code>console.log(new_arr); // ['0', '0', '1']
  </code></pre>
  
  <p><strong>Update</strong></p>
  
  <p>Each array has 3 elements (strings). Whenever <code>'0'</code> is found in any of the two arrays, it must remain in the result.</p>
