How to use and import Observer

[Ramzdam 2 Likes (Newbie)]

One of the answer I found in the forum while searching for the animation I like is to use Observer. Now I don't know how to start or where to begin specially with importing it. I tried 

import { Observer } from "gsap/Observer";
gsap.registerPlugin(Observer);

but it says that its not defined or can't find the class Observer. How do I use this? I saw one post saying I need to use Reactjs or start looking for React. But we are not using Reactjs. We are only using Drupal Twig Template and simple HTML. How can I use this plugin? Can someone share any useful link I can follow? 

 

Thanks in advance

Please don't do that. You do not need React.

 

If you're using modules, then you should do the import thing, otherwise just a <script> tag.

Thanks for this. Just found out that I'm using version 3.9 while Observer is introduced in 3.10
