Webpack newbie: how do I use static js and css files in my app?

When migrating to v4 I thought I should use webpack for better structure of my app. However. I am a complete newbie and I don’t even understand how I use css or js files. I used to include them in tags in my index.html, for example:

<link rel="stylesheet" href="static/c3/c3.css">
<script src="static/js/jquery-3.3.1.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/ionicons.js"></script>

How are those used with webpack? I figured I should import them in app.js but I can’t figure out how.

Read this about import / export ES6, its wery easy

Thanks! And sorry for the late response. I got it all working now!
