What are some real-world use cases for asynchronous programming?

Asynchronous programming is widely used in web development, especially for handling multiple requests without blocking. For example, in a web application, it allows users to continue interacting with the interface while data is being fetched from a server.

Can you give me more examples?

Sure! Other use cases include real-time chat applications, where messages are sent and received without delays, and file uploads, where users can continue working while files are being uploaded in the background.

How does it improve performance?

It improves performance by allowing the program to handle other tasks while waiting for operations like network requests or file I/O to complete, thus making better use of resources and enhancing user experience.

Are there any downsides to using asynchronous programming?

Yes, it can introduce complexity in code management, such as callback hell, and debugging can be more challenging due to the non-linear flow of execution.
