A generic representation of a reducer function.

Reducer functions are pure functions which take a State and Action and return a State.

let reducer: ReducerFn = { (state: State, action: Action) in
    var state = state
    switch action {
        case let action as SetScores:
            state.home = action.game.home
            state.away = action.game.away
            return state
        default:
            return state
    }
}

A generic representation of a selector function.

Selector functions are pure functions which take a State and return data derived from that State.

let selectPost = { (state: AppState) in
    return state.singlePost.post
}
