Docs: local docs site is broken with React 15.6.2

[ayastreb]

Steps

• I do a clean install (rm -rf ./node_modules/ && node install)
• I try to run local docs site for local development
• I run npm start as per contributing.md
• I open http://localhost:8080/ in a browser

Expected Result

• Local docs side is loaded

Actual Result

• I get blank page and JS error Uncaught ReferenceError: React is not defined and HTTP 404 http://cdnjs.cloudflare.com/ajax/libs/react/15.6.2/react.min.js

Looks like it happens because I have React 15.6.2 installed and cloudflare CDN doesn't have this version for some reason.
A workaround could be to lock React to 15.6.1 in package.json, e.g. "react": "15.6.1" instead of "react": "^15.6.1"
Any other ideas? 🤔

Use yarn? 😄 We have lockfile, so you can install deps without any problems. However, now we use three CDNs. I'm think that we can switch to jsdelivr as they have all needed deps.

Hmm, yes, maybe I should finally try using yarn. I assumed yarn and npm are interchangeable and was always too lazy to install yarn 😆

@ayastreb let us know if that worked for you. Performance is better with yarn since it caches packages locally once you've installed them. Additionally, it is just better at consistently resolving packages. Lots of great stuff in there.

@brianespinosa yes, it works with yarn, thanks!

npm has sadly become a mess.
