title: Javascript: Copy Array with filter
body: <p>As I understood there is no best practice for copying an Array in Javascript.</p>
  
  <p>Would it be a could idea to use Array.filter, to copy an Array?</p>
  
  <p>Something like:</p>
  
  <pre><code>var words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];
  const result = words.filter(word =&gt; word);
  </code></pre>
  
  <p>Because filter returns a new Array?
  Are there any disatvantages using this Method?</p>
