You can set up your own global event system for communication between two components that don't have a parent-child relationship, according to the React documentation. When you receive an event, subscribe to it in componentDidMount(), unsubscribe in componentWillUnmount(), and use setState().
Using props, from parent to child.
Callbacks from the child to the parent
Sibling Rivalry: (I) Combine the two procedures mentioned above. (ii) Making use of Redux. (iii) Making use of the Context API in React.
The three main methods of communicating in React are:
The render method - The render method is the most common way of communicating with React, as it tells what should be displayed on the screen by calling on other methods that handle data and logic.
The componentDidMount method - This method is called when the component has been mounted on the DOM, which means that it can be used to initialize state after mounting has occurred.
This pattern can be used in many different ways and there are so many use cases for it. It’s a good idea to have some understanding of this pattern before using it in your next project.
