title: In what cases do javascript developers use the map() method?
body: <p>I'm learning about the map() method right now and I understand very basic examples.</p>
  
  <pre><code>var numbers = [2, 4, 6];
  
  var double = numbers.map(function(value) {
      return value * 2;
  });
  </code></pre>
  
  <p>My question is, in what cases do developers use the map() method to help solve problems? Are there some good resources with real world examples?</p>
  
  <p>Thanks for the help! </p>
