A script you include during development that shows the root, target and intersection every time an IntersectionObserver is triggered.
Import the script from your html:
<script src="https://unpkg.com/intersection-observer-debugger"></script>
Or, install the dependency and import it from JS:
$ npm install intersection-observer-debugger --save-dev
// index.js
import "intersection-observer-debugger"
Make sure to import it before any code that may use the IntersectionObserver constructor.
