When should I use Redux?

In general, use Redux when you have reasonable amounts of data changing over time, you need a single source of truth, and you find that approaches like keeping everything in a top-level React component's state are no longer sufficient. However, it's also important to understand that using Redux comes with tradeoffs.

Accordingly, when should I use Redux with react?

When using Redux with React, states will no longer need to be lifted up; thus, it makes it easier for you to trace which action causes any change. As seen above, the component does not need to provide any state or method for its children components to share data among themselves. Everything is handled by Redux.

Furthermore, why do we use Redux? Redux is used mostly for application state management. To summarize it, Redux maintains the state of an entire application in a single immutable state tree (object), which can't be changed directly. When something changes, a new object is created (using actions and reducers).

What are react hooks?

Should I use Redux with angular?
