(function (global, factory) {

This code seems to be duplicated in your project.

  typeof exports === 'object' && typeof module !== 'undefined' ? module.exports = factory(require('jquery'), require('./util.js')) :
  typeof define === 'function' && define.amd ? define(['jquery', './util'], factory) :

The variable define seems to be never declared. If this is a global, consider adding a /** global: define */ comment.

  (global = typeof globalThis !== 'undefined' ? globalThis : global || self, global.Tab = factory(global.jQuery, global.Util));

The variable globalThis seems to be never declared. If this is a global, consider adding a /** global: globalThis */ comment.

If you intend to check if the variable self is declared in the current environment, consider using typeof self === "undefined" instead. This is safe if the variable is not actually declared.

Usage of the sequence operator is discouraged, since it may lead to obfuscated code.
