NOTES

mapStateToProps

redux mapStateToProps has a shallow 
equality check for every value in the object; 
it won't replace values if they pass a shallow equality 
check which means it won't needlessly re-render,
but if we have transformation logic it's still valuable 
to memoize it with a selector to save us running 
duplicate logic to get the same output.

async fetches in useEffect

useEffect(() => {
  const genAsyncFunction = async () => {
    const asyncRes = await myOtherAsyncFunction()
    // do something with asyncRes (setX, contextUpdate, etc)
  }
  getAsyncFunction()
},  [])

FIREBASE BACKWARDS COMPAT FOR IMPORT ERROR:
