Prayer timetable made with React

import { GET_TIMETABLE } from '../constants/actionTypes'
import initialState from './initialState'

// IMPORTANT: Note that with Redux, state should NEVER be changed.
// State is considered immutable. Instead,
// create a copy of the state passed and set new values on the copy.
// Note that I'm using Object.assign to create a copy of current state
// and update values on the copy.
const timetableReducer = (state = initialState.timetable, action) => {
  switch (action.type) {
    case GET_TIMETABLE:
      // For this example, just simulating a save by changing date modified.
      // In a real app using Redux, you might use redux-thunk and handle the async call in fuelSavingsActions.js
      return { ...state, timetable: state.timetable }
