What is the purpose of Redux saga
Redux Saga is a middleware library that enables a Redux store to interact asynchronously with resources outside of itself, including accessing browser storage, sending HTTP requests to external services, and performing I/O operations (also known as side effects).
What is the advantage of Redux saga
Redux-saga is a middleware that acts on an action before it reaches the reducer, handling all side effects and giving you more control over the effects. This creates a clear separation of concerns because the middleware will handle the side effects, not the component.
Why do we use Redux thunk
Redux Thunk is a middleware that enables you to call action creators that return a function rather than an action object. Once the asynchronous operations have finished, the function receives the stores dispatch method and is used to dispatch regular synchronous actions inside the functions body.
What are the differences between call and put in Redux saga
The functions call() and put() both create effects; call() creates an effect description that tells middleware to call the promise, and put() creates an effect that tells middleware to send an action to the store.
What is redux thunk in React JS
Redux Thunk middleware enables you to create actions that return functions rather than actions. The inner function receives the store methods dispatch and getState as parameters. The thunk can be used to delay the dispatch of an action or to dispatch only if a certain condition is met.
What is difference between Context API and Redux
Both are excellent tools for their own specific niche, Redux is overkill just to pass data from parent to child & Context API truly shines in this case.

What is generator function saga
Sagas are implemented as Generator functions that yield objects to the redux-saga middleware. When a Promise is yielded to the middleware, the middleware will suspend the Saga until the Promise completes.
What is action creator in Redux
In Redux, action creators simply return an action object and pass the argument value if necessary. An action creator is a function that actually creates an action object.
What is Redux toolkit
Redux Toolkit is our official, opinionated, battery-included toolset for effective Redux development, and we strongly urge you to use it. It is designed to be the standard way to write Redux logic.
What is Redux library
How install Redux saga in React native
Step-By-Step: How to Add Redux Saga to a React & Redux App
- npm install redux-saga is the first step.
- Import the libraries in /src/configure-store in step 2.
- Create a root saga in /src/configure-store in step three.
- Create a saga middleware instance in step four.
- Apply the Saga middleware to Redux in Step 5.
- Run the saga in step six.
What is use of Redux in React JS
Its intended usage adopts the design principles of React – writing declarative components. As the official Redux binding for React, React Redux is kept up-to-date with any API changes from either library, to ensure that your React components behave as expected.
What is middleware React
There may be several middleware that an action runs through before ending in a reducer. Middleware allows for side effects to be run without blocking state updates. We can run side effects (like API requests) in response to a specific action or in response to every action that is dispatched.
Is redux saga necessary
Redux-observable and redux-saga both make use of reactive programming and generators; both are incredibly interesting and useful concepts, but neither is necessary in order to make that API request, to put it simply.
What is the difference between redux and redux saga
Redux is more widely accepted than redux-saga, which is listed in 43 company stacks and 21 developer stacks. Redux is mentioned in 1036 company stacks and 832 developer stacks.
What is redux saga vs thunk
Redux Saga allows you to send actions normally, but it also has a watcher that catches each action as it is dispatched, unlike thunk where action creators return functions rather than objects.
What is redux saga in React native
Because redux-saga is a redux middleware, it has access to the complete redux application state, can dispatch redux actions, and can start, pause, and cancel this thread from the main application.
What is the mental model of redux Saga
The redux-saga documentation states that “the mental model is that a saga is like a separate thread in your application thats solely responsible for side effects.” Redux saga is a middleware that you can plug into your Redux store to soup it up a little bit.
