With React, developers can create small, reusable components that are easy to maintain and update. In this video, we will dive into the data passing mechanism of React and show how it can be used with Redux.
Data Passing in React:
Data passing is sending data from one component to another during the render phase of a component's lifecycle. Components need to share data so that they can react appropriately when certain events happen in the app.
React uses two different approaches for handling data flow: props and state.
Props are passed down from one component to another via props, and state is passed down via state or props depending on whether it is an initial state or not (initial states are passed down via props).
State and props are the two different approaches for handling data flow between components. The state approach is central to React, while the props approach is more common in Flux-based architecture.
The state of a Redux app has one big tree with all the data in a single store and one root component which manages this data. All the other components get information from the store. So the state tree has a single source of truth, and all the data gets pulled down from this source.
The props approach is more common in Flux-based architecture, where there is one global dispatcher that manages data flow between components.
Not every piece of data must be in the component where we wish to render it. So, even if you create a 1- to 2-page application, we still need to ensure that the components communicate with one another since data passing between two components is crucial.
This tutorial will show different subscriptions with different data using the same component.
In this video, we will reuse the same component multiple times in an app. For example, let's say we have three subscriptions with different data. We want to show them all on one screen and make it easy for the user to switch between them.
We will use a component that has been designed for this purpose and create three instances of that component and attach each subscription to it. This way, the user can easily switch between subscriptions by clicking on one of these components.

The data flow in React is one-way. Props are passed down from parent components to their offspring. Props cannot be passed up to the parent component by children components. Callback functions can be passed as a prop to allow children components to make modifications to their parent component.
Data passing is an essential mechanism that helps us move information around a React application. It is used by most of the React libraries and frameworks such as Redux or MobX.
Data passing is an important concept in React. It allows us to make changes on the fly without worrying about updating our UI.
Data passing is the way that React components communicate with each other. It is a core concept of React and it helps in making the app more organized and efficient.
There are three different types of data passing in React: props, state, and refs.

Data passing in React is a mechanism through which data travels from one component to another. It's a way of sharing data between components, a fundamental concept in any React application.
If you're looking for ways how to pass data in React, then, Data passing in React can be achieved by using props, state, or event handlers. Props are the most widely used because they provide an easy way for developers to pass data from one component to another without relying on explicit state management. Event handlers can also be used, but they require more work because they have less flexibility and control over data flow.
React components are the building blocks of a React application. In order to make use of the data in your application, you need to pass data between your components. Here are a few ways to pass data between React components.
Data passed via props: Props are passed from one component to another and are usually used for passing information about the component's state or its properties. They can also be used to pass information about events that happen on the component.
Data passed via state: The state of a React component can be updated with data that comes from an outside source. This data could be anything like an event, a server response, or even the result of a calculation. The state can then be passed to another part of the application via props.
Data passed via events: React provides an event system that allows you to pass data between components in your application easily. This enables you to do things like update a component's state based on an event from another component or send data from one component down through the hierarchy of components and then back up again.
Data passed via refs: Refs are used when you want to access a private property on another component without having it exposed publicly or when you want to access a public property on another component without having it exposed privately.
In React, data can be passed between pages using a higher-order component.
Higher order components are functions that wrap other functions and return a new function. They take the props from the wrapped function as arguments and return a new function that takes the same props as its arguments.
A higher-order component is like a regular React component, except it does not create any DOM elements or render anything on its own. Instead, it just wraps some other function so it can pass data to or receive data from it.
The Higher Order Component pattern has been around since before React was even created, but since then, many libraries have been built on top of this pattern to provide you with more functionality out of this one concept.
