What are some examples of types in Redux?

Can you give me some examples of types used in Redux?

Sure! In Redux, types are often defined as constants to avoid typos. For example, you might have types like 'ADD_TODO', 'REMOVE_TODO', and 'TOGGLE_TODO'.

How do I define these types in my code?

You can define them in a separate file, like 'actionTypes.js'. For instance:

export const ADD_TODO = 'ADD_TODO';
export const REMOVE_TODO = 'REMOVE_TODO';
export const TOGGLE_TODO = 'TOGGLE_TODO';

What about using TypeScript with Redux?

When using TypeScript, you can define types for your actions and state. For example:

interface AddTodoAction {
  type: typeof ADD_TODO;
  payload: string;
}

Can you show me a complete example?

Absolutely! Here's a simple example of a Redux setup with types:

// actionTypes.js
export const ADD_TODO = 'ADD_TODO';

// actions.js
import { ADD_TODO } from './actionTypes';

export const addTodo = (todo) => ({
  type: ADD_TODO,
  payload: todo,
});
