title: LoDash _.has for multiple keys
body: <p>Is there a method or a chain of methods to check if an array of keys exists in an object available in lodash, rather than using the following?</p>
  
  <pre><code>var params = {...}
  var isCompleteForm = true;
  var requiredKeys = ['firstname', 'lastname', 'email']
  
  for (var i in requiredKeys) {
      if (_.has(params, requiredKeys[i]) == false) {
          isCompleteForm = false;
          break;
      }
  }
  
  if (isCompleteForm) {
      // do something fun
  }
  </code></pre>
