- Responsiveness: Asynchronous tasks keep the app responsive, preventing it from freezing during time-consuming operations.
- Improved User Experience: Users enjoy a seamless experience without interruptions, making them more likely to engage with the app.
- Efficiency: Background tasks can run concurrently, optimizing resource utilization and reducing processing time.
While callbacks are fundamental, managing multiple asynchronous operations with callbacks alone can lead to complex and error-prone code, known as "callback hell." Promises provide a more structured and readable approach to asynchronous flow control. They allow developers to chain operations, handle success and error cases more elegantly, and simplify error handling.
Image Loading: In a mobile app, images are often loaded asynchronously to prevent blocking the UI. Asynchronous image loading ensures that users can continue interacting with the app while images are fetched from a server or cached locally.
Data Synchronization: Mobile apps frequently synchronize data with remote servers. Asynchronous data synchronization allows this process to occur in the background, ensuring that users can access up-to-date information without disruptions.
