Otherwise, return the existing state unchanged.

If so, make a copy of the state, update the copy with new values, and return it.Check to see if the reducer cares about this action.The logic inside reducer functions typically follows the same series of steps:

We'll talk more about the rules of reducers later, including why they're important and how to follow them correctly.

They must not do any asynchronous logic, calculate random values, or cause other "side effects".

Instead, they must make immutable updates, by copying the existing state and making changes to the copied values. They are not allowed to modify the existing state.They should only calculate the new state value based on the state and action arguments.Reducers must always follow some specific rules: "Reducer" functions get their name because they're similar to the kind of callback function you pass to the Array.reduce() method. If I create an array, I can change the contents as well: If I create an object, I can change the contents of its fields. JavaScript objects and arrays are all mutable by default. If something is "immutable", it can never be changed.

This is the basic idea behind Redux: a single centralized place to contain the global state in your application, and specific patterns to follow when updating that state to make the code predictable. With this, our component tree becomes a big "view", and any component can access the state or trigger actions, no matter where they are in the tree!īy defining and separating the concepts involved in state management and enforcing rules that maintain independence between views and states, we give our code more structure and maintainability. One way to solve this is to extract the shared state from the components, and put it into a centralized location outside the component tree. Sometimes this can be solved by "lifting state up" to parent components, but that doesn't always help. However, the simplicity can break down when we have multiple components that need to share and use the same state, especially if those components are located in different parts of the application.

The UI re-renders based on the new state.

When something happens (such as a user clicking a button), the state is updated based on what occurred.

State describes the condition of the app at a specific point in time.

This is a small example of "one-way data flow":

The actions, the events that occur in the app based on user input, and trigger updates in the state.

The view, a declarative description of the UI based on the current state.

The state, the source of truth that drives our app.

It is a self-contained app with the following parts: SetCounter ( prevCounter => prevCounter + 1 ) Action: code that causes an update to the state when something happens
