Although as web developers, we’re quite used to writing them, we write it differently to most of the code we write. In other areas we strive for DRY, reusable code with single responsibilities. But in front-end, we write highly specialised, tightly coupled, multi-responsibility code to achieve simple tasks. In simpler applications, where only a local component-level state is needed, Redux can be overkill and slow development time while increasing the code base’s complexity. Similarly, if an application uses server-side rendering or has minimal dynamic functionality, Redux may also be unnecessary. In these cases, developers will be more efficient using a component-level state instead of introducing Redux into their web app stack.
Reducers are pure functions that take the current state of an application, perform an action, and return a new state. The reducer handles how the state (application data) will change in response to an action. As shown in the image, Redux takes away the responsibility from individual components to manage a state. Instead, we create a single store that handles our state management. On top of that, all communication regarding reading, updating, or creating data happens via the store. Moreover, components can listen to state changes to update the UI and avoid these data inconsistency bugs.

The looseness with which React can be employed is great for experimentation, but challenging when you’re trying to do things the right way. Knowing there isn’t one yet will save you some time here. Notice that in the above code the markup is inside your JS class, and your css is imported at the top as well. It’s unusual, and many developers have a hard time getting used to it, but once you get over your preconceptions it becomes extremely familiar. It studies the Flux architecture and removes unnecessary complexity. If we dig deeper into this statement, we see that Redux is a state management library that you can use with any JS library or framework like React, Angular, or Vue.
When you update your state with Redux, you always start with an action. Actions are in the form of Javascript objects, containing a type and an optional payload. Redux is a lightweight state management tool for JavaScript applications, what is redux for released in 2015 and created by Dan Abramov and Andrew Clark. State, a term from React, is an object that holds data contained within a component. State is a central component to making dynamic pages through conditional rendering.

State management is essentially a way to facilitate communication and sharing of data across components. It creates a tangible data structure to represent the state of your app that you can read from and write to. That way, you can see otherwise invisible states while you’re working with them. Also, you can avoid using Redux if your data comes from a single data source per view. In other words, if you don’t require data from multiple sources, there’s no need to introduce Redux.
Hey everyone, I am a new self-taught developer and have some questions regarding apps. I apologize in advance if the question is too obvious or simple. We can persist some state of the application to local storage and restore it after refresh. STORE：The Store is where the entire state of the application is listed. It manages the state of the application and has scheduling capabilities.
