owlCarousel2 is a jQuery plugin written in an IIFE pattern.
Plugin initialization relies on jQuery in global object.
Most users face an issue like TypeError: $ is undefined thrown by the plugin bundled with browserify, webpack or other bundlers, because jQuery isn't attached to the global object by default in a module execution context. It makes users to expose jQuery to global object what can be harmful - overwriting another version of jQuery which the rest of the code relies on.
Here's a small CommonJS wrapper which handles this issue.
It preserves existing jQuery, then exposes our jQuery, initializes owlCarousel2, and, in the end, exposes preserved jQuery back (if there was one before).
