How React Props and Redux Actually Work, Step by Step

A simple look at what happens when you click a button in React, how data moves from parent to child, and what changes when you add Redux. It looks simple You write onClick={() => setCount(count + 1)} . You click the button. The number on the screen changes. It feels fast and simple. But under the hood, React follows the same steps every time. Once you know these steps, React makes a lot more…

React props and Redux are two different ways to manage data flow in a React application. In React, props are used to pass data from a parent component down to a child component. When you click a button and call setCount(count + 1), React saves this request for later and only re-renders the component once with the final value, rather than re-rendering multiple times on each state update. This is known as batching updates.

Redux, on the other hand, is a separate library that allows data to flow more freely throughout the entire application. By using Redux, you can store state in a single store and make it accessible to any component in the application. Redux uses four main parts: a slice to define the initial state and how it can change, a store to hold the state, a provider to make the store available to all components, and any component that wants to use the state. This allows for more centralized and predictable state management in a large application.
