title: React Native importing only what is needed
body: <p>Say I have the following:</p>
  
  <pre><code>import validator from 'validator'
  </code></pre>
  
  <p>and in my code do:</p>
  
  <pre><code>validator.isEmail(txt)
  </code></pre>
  
  <p>Would that import the entire <code>validator</code> and increase the overall package size?</p>
  
  <hr>
  
  <p>if, how do I avoid this?</p>
