API

// create a new local state value in a React function component
const count = createHook(0)

// same, but with initializer function
const {state,setState} = createHook(() => 0)


// change the state with to the given value
setState(0)

// update the state using an updater function, that receives the current state and returns the next one
count(c => c + 1)
