What is the difference between async and multi-threading?

Async programming allows tasks to run concurrently without blocking, while multi-threading uses multiple threads to execute tasks simultaneously.

Can you give me an example of when to use async?

Sure! Use async for I/O-bound tasks like web requests, where waiting for a response can be done without blocking the main thread.

And when should I use multi-threading?

Multi-threading is ideal for CPU-bound tasks, like heavy computations, where you want to utilize multiple cores for better performance.

Are there any downsides to using either approach?

Yes, async can lead to complex code with callbacks, while multi-threading can introduce issues like race conditions and increased memory usage.
