List core-js as a dev dependency to install when working with React

[kojidev]

I've been following the steps of integrating the Redoc into react app, and it asks to install styled-components and mobx above react and react-dom, but the code also uses core-js/es6/promise module but it is not listed in installation doc.

[brendancf]

is there a workaround or fix for this?

@brendancf just add it into your project as a dependency, my issue is that it is not listed anywhere, you have to figure out yourself

npm install es6-promise

OK, I removed core-js and removed node_modules and package-lock.json then reran npm install and its working now.
