title: Find a value in an array inside other array with lodash
body: <p>I have an array such as:</p>
  
  <pre><code>var db = [{
          "words": ["word1a", "word1b", "word1c"],
          "answer": "answer1"
      }, {
          "words": ["word2a", "words2b"],
          "answer": "answer2"
      }]
  </code></pre>
  
  <p>I'm using lodash on node.js to check values in an array. I want to search words and return an response. For example, if I search "word1a", the response is "answer1"</p>
  
  <p>I try:</p>
  
  <pre><code>var e = _.find(db, function(o){
      o.words === "say"
  });
  console.log(e);
  </code></pre>
  
  <p>But I cant find a result;</p>
  
  <p>Obviously, I get undefined because I'm comparing an exactly value. How can I get the value?</p>
