first things first

atom.io owes its existence to Recoil.

The Recoil tutorial is generally applicable to atom.io, as long as keep in mind that

• atom.io reimplements the model of atom and selector directly from Recoil.
• Like Recoil, atom.io is great in React apps, but
  • useO <- useRecoilValue
  • useI <- useSetRecoilState
  • There's no useRecoilState
  • You don't need <AtomIOProvider/> to use atom.io in a React app.
• Unlike Recoil, atom.io is not bound to React.
  • You can use getState and setState anywhere, not just in React components.
• transaction is its own thing in atom.io and it's a stable part of the API
