Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

Babel includes JSX processing.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

                // This is a ZIM comparison to the well coded VUE pen: 
// https://codepen.io/d-antonelli/pen/GRpQrOY
// Cheers to the original creator!
// The ZIM Code is 40% the VUE code and probably more direct 

// Here is a comparison to another VUE rocket pen at 1/3 the size of VUE:
// https://codepen.io/zimjs/pen/oNjqxKz

// This type of size reduction is very common with ZIM 
// See the end of the ZIM intro video 
// https://www.youtube.com/watch?v=EB66-QgUz98

// We would much rather code rockets more dynamically - such as:
// https://codepen.io/zimjs/pen/EzpOPP
