title: Convert all object values to lowercase with lodash
body: <p>I have an object:</p>
  
  <pre><code>z = {x: 'HHjjhjhHHHhjh', y: 'YYYYY', c: 'ssss'}
  </code></pre>
  
  <p>I need to convert all values to lowercase</p>
  
  <pre><code>z = {x: 'hhjjhjhhhhhjh', y: 'yyyyy', c: 'ssss'}
  </code></pre>
  
  <p>How to do this in one time, maybe with lodash? for now I am doing:</p>
  
  <pre><code>z.x = z.x.toLowerCase()
  z.y = z.y.toLowerCase()
  z.c = z.c.toLowerCase()
  </code></pre>
