title: Check if a text exists in a value in deep nested object?
body: <p>How is it possible to check if a deep nested object containing a value?
  I want to check if the given object contains for example, a property value that contains "where" :</p>
  
  <pre><code>let data = {
      name: 'Somebody',
      address: {
          city: 'somewhere'
      },
      tags: [{
          id: 5
          name: 'new'
      }]
  }
  check(data, 'where') // should be true
  </code></pre>
