title: why can't lodash find the max value from an array?
body: <p>I have below code and I tried to use <code>lodash</code> to find the max value from an array object;</p>
  
  <pre><code>var a = [ { type: 'exam', score: 47.67196715489599 },
    { type: 'quiz', score: 41.55743490493954 },
    { type: 'homework', score: 70.4612811769744 },
    { type: 'homework', score: 48.60803337116214 } ];
   var _ = require("lodash")
  
   var b = _.max(a, function(o){return o.score;})
   console.log(b);
  </code></pre>
  
  <p>the output is <code>47.67196715489599</code> which is not the maximum value. What is wrong with my code?</p>
