Prop drilling is a technique used in React to pass data from a component to its descendant components through props. This technique involves passing props down through multiple levels of nested components until they reach the component that needs the data.
For example, consider a React app that displays a list of items. Each item has a title and a description. The top-level component renders the list of items, and each item is rendered by a separate component. If the title and description of each item are stored in the top-level component's state, the state data must be passed down through multiple levels of nested components to reach each item component. This is an example of prop drilling.
While prop drilling is a straightforward and effective way to pass data between components, it can become cumbersome and error-prone as the number of levels in the component tree grows. Passing data through multiple levels of components can also result in a lot of boilerplate code and make it difficult to maintain and refactor the codebase.
To address these issues, React provides a number of other techniques for managing state and passing data between components, including context, Redux, and GraphQL. These techniques can help simplify the code and reduce the need for prop drilling.
