const isLoading = true // Great, we know we know something is loading
const isLoading = false // We only know we're not loading, ANYTHING ELSE IS POSSIBLE

// In symbolic logic, this is referred to as a _modus tollens_
// the negation of an assertion only tells us that _that_ particular thing
// in the universe is negated, it conveys _no_ logical information about anything else

// Ex. If I have a Mtn Dew in front of me, I will drink it.
// I do _not_ have a Mtn Dew in front of me, therefore I can't assert anything
// about anything I am doing other than _not_ drinking a Mtn Dew

// It is better to enumerate states than to boolean-ate states (Yes, I may have made that up)
const STATES = { idle, loading, success, failure }

// Now there is no confusion regarding what it means when I check what state I'm in

if (currentState === STATES.loading) { doSomething() }

// Also, this has the benefit of being able to respond conditionally to states with other enums

const TEXT_RESPONSES = {
  idle: `I'm chilling`,
  loading: 'Loading...',
  success: 'Huzzah!',
  failure: 'Womp, womp...'
}

const currentState = STATES.success
const displayText = TEXT_RESPONSES[currentState] // Huzzah!

// Enjoy!
