title: How to remove a programatically loaded reCAPTCHA V2?
body: <p>On an ajax-based or js-based website or a single page application you can call <code>grecaptcha.render('targetId', ...)</code> to create the reCAPTCHA element on demand. </p>
  
  <p>But how can you remove it once the reCAPTCHA is no longer needed?  </p>
  
  <p>Creating and deleting the reCaptcha HTML by switching routes leads to a "memory leak".  </p>
  
  <p>I am looking for something like <code>reCaptcha.destroy()</code>.</p>
