Getting Started with Redux

Principles:

  1. whether your app is a simpleton or a huge one. The state of the app is a single javascript object.
  2. The state tree is redundant. You can’t modify or write to it. instead anytime you want to change the state you need to dispatch an action.
  3. To describe state mutations, you have to write a function that take the current state and the action being dispatched and returns the next state. And this function has to be pure. This functions is called Reducer.
  • State: The minimal representation of the data in your app.
  • Action: a plain JavaScript object describing the change. The minimal representation of the change to the state.
