Restrict state transitions according to graph

Should switch reducers based on the current state in order to ensure that the program can’t enter bad states.

• For each state, build a reducer that only responds to transitions listed for that state in the state graph
• Create a parent/meta reducer that switches the invoked child reducer based on the current state

Sample state graph:

const fetchingStates = [
  ['initialize', 'idle',
    ['fetch', 'fetching',
      ['cancel', 'idle'],
      ['report error', 'error',
        ['handle error', 'idle']
      ],
      ['report success', 'success',
        ['handle success', 'idle']
      ]
    ]
  ]
];

Okay, I think I get it completely. Let me think on it, and maybe I’ll attack it tomorrow. Thanks for your time and help understanding this!
