Prop drilling is a technique in React where props are passed from one part of the tree to another by going through other parts that do not need the data, but are merely passing it along. This is commonly seen in larger applications where there is a significant amount of nested components.

Here are the steps to understand prop drilling:

1. Create a context in the parent component.
2. Pass the state and the function to change it as props to the child component.
3. The child component then passes these props to the grandchild component.
4. The grandchild component can then use these props to display the state and change it.

Potential setbacks of prop drilling:

1. Code complexity: Prop drilling can lead to increased complexity in the code, making it harder to understand and maintain. It can be especially difficult to track where the props are coming from when they are passed through multiple layers.

2. Performance issues: Every time the state changes, all components receiving the props will re-render, even if they don't use the props. This can lead to performance issues in larger applications.

3. Code redundancy: If many components need the same data, you'll have to pass the props through all these components, leading to code redundancy.

4. Refactoring: If you need to move a component to a different part of the component tree, you'll have to move all the props as well. This can make refactoring more difficult.

To overcome these setbacks, you can use Context API or state management libraries like Redux or MobX, which allow you to manage and access state from any component without having to pass props through intermediate components.
