title: Underscore equivalent of Lodash _.get and _.has
body: <p>I am trying to have search for Underscore equivalent for Lodash <code>_.get</code> and <code>_.has</code>, where it is able to directly access the existence and value of nested object value without the need of checking the existence of its parents.</p>
  
  <p>However, it seems to me that underscore <code>_.get</code> and <code>_.has</code> only able to check the value for the first level.</p>
  
  <pre><code>var object = { 'a': { 'b': 2 } };
  _.has(object, 'a.b'); // lodash shows true
  _.has(object, 'a.b'); // underscore shows false
  </code></pre>
