What is the difference between state and props in React?

I’m trying to understand the difference between state and props in React. Both seem to be used for managing data in a component, but I’m unclear about how they differ in terms of functionality and usage. Could someone explain this clearly?

State  Props

State is a built-in object that stores property values that   belong to the component. It's used to maintain data that can change over time.

Props (short for properties) are a way of passing data from parent to child components. They are one-way, meaning data flows from parent to child only.                                                                   

State is mutable, meaning it can be changed or updated asynchronously, usually by using the setState function in class components or the useState hook in functional components.

Props are immutable from the perspective of the component receiving them. A component should not modify its own props.

State is local to the component in which it is declared. It cannot be accessed or modified directly by child components, although you can pass state values down to children via props.

Props are read-only and are meant for transferring data and event handlers down the component tree. They allow customization of child components based on data from parent components.

Ideal for data that needs to be tracked or modified in response to user actions or system events within the component. For example, form input values, toggled elements, etc.

Ideal for passing static data or callbacks to child components so that they can operate on data or notify the parent of events.
