Hi Kent 👋

I worked on creating this series with my friend @metagrover. We're using react-testing-library for testing. The source code is at https://github.com/wtjs/tooltip

I noticed that I wasn't able to run the setup with Node 10 stable. Also when running validate I get some errors:

[build] src/index.js -> dist/index.js
[build] npm run build --silent exited with code 0
[test]  FAIL   library  src/__tests__/debug.js
[test]   ● Test suite failed to run
[test]
[test]     SecurityError: localStorage is not available for opaque origins
[test]
[test]       at Window.get localStorage [as localStorage] (node_modules/jsdom/lib/jsdom/browser/Window.js:257:15)
[test]           at Array.forEach (<anonymous>)

Although they shouldn't be related to this PR, thought would just let you know.

Thanks!

@divyanshu013 , actually Jsdom was updated a few days back and they have introduced this new localstorage check, you can bind the jsdom version to previous one in your projects' package.json. Please ignore if you have already have a solution for the same. I also ran into similar issue few days back.
