When using Render Props, which React concept allows the parent to access the state of the child component?

When using Render Props in React, the parent can access the state of the child component through component refs. By creating a ref to the child component, the parent can directly interact with its state and methods, allowing for more dynamic and interactive behavior. While Context API can be used for state management in React, it is not the primary mechanism for accessing a child's state when using Render Props.
