Props in a React component are intended to store information that can be changed by the component itself.

Explanation:
Props are inputs from a parent to a child and are meant to be read by the child, not changed by it. In React, data flows one way: from parent to child, and props are treated as immutable inside the component. If you need to reflect changes, store the value in the component’s own state or have the parent update the prop by calling a callback (lifting state up). Mutating a prop (even if it’s an object or array) is an anti-pattern because it can lead to bugs and won’t reliably trigger re-renders; instead, create new values when updating and pass them down. So the statement is false.
