If that’s the argumentation then Postgres is over 22 years old which makes it over two times better? On the other hand Windows is over 30 years old and it still hasn’t fixed many issues which for me are the reasons why I don’t want to have anything to do with it.

I'm not saying MongoDB is better because it is old, and I was rather hoping you would elaborate. For all I know, you could have had issues with it yesterday or 9 years ago.

I urgently encourage you and anyone else reading this to check out Turbolinks 5, ideally in tandem with Stimulus. https://www.youtube.com/watch?v=SWEts0rlezA&t=3m22s https://github.com/turbolinks/turbolinks https://stimulusjs.org/ You can get all of the benefits of server-generated pages with the speed of an SPA. 90%+ of the sites built using SPAs would be better served by Turbolinks and Stimulus.

I've never heard of either before, and they've really caught my attention. Thanks for bringing this up.

I'm not exactly clear on what you're looking for. Reducers, by definition, take two parameters: the current state and the action. They should return an updated state based on those two inputs only. The `payload` field is simply a common convention for consistently putting the "arguments" or "data" for that action type at a known key in the action each time. I'm also not sure what you mean by "calling actions should w…

Look at the sample code in https://redux-starter-kit.js.org/api/createslice Since all actions contain just one parameter, it's easy to confuse things, so let's add a multiplyAdd function to multiply the counter by 'a' and then add 'b'. It would look like this: multiplyAdd: (state, action) => state * action.payload.a + action.payload.b I want it to look like: multiplyAdd: (state, a, b) => state * a + b or even multipl…

  const

  create_store = ({state, actions}) => {
    const

    after_update_do = [],

    subscribe = fn => after_update_do.push(fn),

    notify = () => after_update_do.forEach(fn => fn(state)),

    create_action = action => (...args) => {
      state = action(state, ...args);
      notify()
    };

    return Object.entries(actions).reduce((bound_actions, [action_name, action]) => 
      Object.assign({}, bound_actions, {[action_name]: create_action(action)}), 
      {subscribe})
  },

  counter = create_store({
    state: 0,
    actions: {
      increase: state => state + 1,
      
      decrease: state => state - 1,

      multiply_add: (state, a, b) => state * a + b,
    },
  });

  counter.subscribe(state => console.log('First reactive component was updated with: ' + state));
  counter.subscribe(state => console.log('Second reactive component was updated with: ' + state));

  counter.increase();
  // First reactive component was updated with: 1
  // Second reactive component was updated with: 1

  counter.multiply_add(2, 3)
  // First reactive component was updated with: 5
  // Second reactive component was updated with: 5
