What is the difference between state and props in React?

State is a built-in React object that stores data specific to a component. It is mutable and can be updated using the setState method. State is used to manage dynamic data that changes over time, such as user input or API responses.

Props (short for properties) are read-only data passed from a parent component to a child component. They are immutable and cannot be modified by the child component. Props are used to pass data and event handlers between components.

In full-stack development, state and props are essential for building interactive UIs. For example, a React component might use state to manage a form’s input values and props to receive data from a parent component or API.
