Obfuscate mailto: email links with base64 encoding and Javascript (blade file for example)

email.blade.php

<a class="email" data-target="{{ base64_encode($email) }}" href="#">Email</a>

email.js

let elements = document.getElementsByClassName('email');

for(let i = 0; i < elements.length; i++) {
  var element = elements[i];
  element.onclick = function(e) {
    e.preventDefault();
    // converts back from base64 and launches the link
    window.location = 'mailto:'+atob(e.originalTarget.dataset.target)
  }
}
