'React.js 'Lifting State Up' Explained' by RashadToure hirereactjsdevelopers react
Lifting state up in React is a key feature that most React.js beginners struggle with. It's quite normal for a beginner starting to learn a framework or a new language to struggle with some concept surrounding certain functionalities. With “Lifting State Up” in React.js, it is very handy in building a scalable front-end of an application.Most beginners in the quest to learn how props works, can easily understand how content is passed from a parent component to its child component.
In a React.js application, if two components are not directly related, you cannot pass data generated between the two components. For example in our demo app, data cannot be shared between “New Expense Component” and “Expense Component”. We can only communicate from child to parent and from parent to child.
To be able to communicate between these two components, the data needs to pass through the closest parent which has access to these two child components. The App Component in our case has direct access to both the “New Expense Component” and the “Expense Component”. So now we can pass our generated state data from “New Expense Component” to the “App Component”.
Then subsequently pass the state data generated by the “New Expense ” to the “Expense Data” through the “App Component”. We do this utilizing props.
