title: Create chain in lodash with custom functions
body: <p>Is there way to get my own custom function in a chain of lodash. So for example like this:</p>
  
  <pre><code>var l = [1,2,3]
  var add = function(a, b){return a+b}
  
  var r =_.chain(l).find(function(a){return a&gt;1}).add(5).value()
  
  =&gt;r = 7
  </code></pre>
