Perfect error handler :)

drupal-troll-overflow.js

(function ($, Drupal) {
  'use strict';

  /**
   * @type {Drupal~behavior#ben_stackOverLowl}
   */
  Drupal.behaviors.ben_stackOverLowl = {
    attach: function (context, settings) {
      try {
        // Ton code ici
      } catch (e) {
        window.location.href = "https://stackoverflow.com/search?q=[js]+[drupal]" + e.message;
      }
    }
  };
}(jQuery, Drupal));
