Thanks for the PR, I just merged this into master!

I took the liberty to modify some comments and also change the mock you added, I think it was invoked even when not necessary, but besides that, everything was neat 👍

This will be published in the next intro.js-react v0.2.0 release which will be released when intro.js v2.8.0 is out of alpha (altho, if you really need the feature right now, you can still use the master branch in your package.json until then).

I also took your suggestion of adding a proper Prettier configuration as it's now supported.🎉 .

Would you be able to tag the commit with the prerelease? Yarn is not picking it up as of right now

[HiDeoo]

Strange, what did you try?

I just tried (I removed the package before each try to be sure):

yarn add https://github.com/HiDeoo/intro.js-react
yarn add https://github.com/HiDeoo/intro.js-react#master
yarn add https://github.com/HiDeoo/intro.js-react#a475b79

and the 3 commands work and pickup the code with the latest changes from master so if even specifying a specific commit number don't work, I don't think a tag would. Maybe it's an issue in Yarn or a specific version of Yarn (for info I use v1.3.2)?

Ah okay. I was trying to use an alpha release tag even though you haven't done an alpha release tag. I'll just that. Thanks.
