redux OOP way

redux-oop.js

const reducers = {
   add(state, {payload: [number]}) {
	     return state + number;
   },
};

function reducer(state, action) {
	 if (reducers.hasOwnProperty(action.type))
		   return reducers[action.type](state, action);
   return state;
}

const store = Redux.createStore(reducer, 0);

// ES6 proxy approach 
// but you can achieve it without proxy
const actions = new Proxy(reducers, {
  get(target, type) {
    return (...payload) => store.dispatch(Object.assign({type}, {payload}));
  }
})

actions.add(10);
actions.add(3);

console.log('state', store.getState()); // 13
