React interview questions in Hindi #5 What is the difference between state and props
1State is a data structure that starts with a default value when a Component mounts. It may be mutated across time, mostly as a result of user events.

Props (short for properties) are a Component's configuration. They are received from above and immutable as far as the Component receiving them is concerned. A Component cannot change its props, but it is responsible for putting together the props of its child Components.
Definition: State is used to manage and store mutable data within a component. Unlike props, state is private to the component that owns it and can be changed within that component.
Accessing State: In class components, state is accessed using this.state, and in functional components, state is managed using React Hooks, such as useState.
Updating State: State can be modified using the setState() method in class components or the state update function returned by the useState hook in functional components. When state is updated, React will re-render the component and its children to reflect the changes.
Props are passed from parent to child components and are read-only, while state is local to a component and can be changed.
Props enable communication between components, whereas state enables components to manage their own data and behavior.
Props flow one-way from parent to child, while state remains within the component where it is defined.Please do like share and comment if you like the video please do hit like and if you have any query please write it comment box
