Asynchronous Programming vs Multi-Threading: What's the Difference?

What is the difference between asynchronous programming and multi-threading?

Asynchronous programming allows tasks to run independently without blocking the main thread, while multi-threading involves multiple threads executing tasks concurrently.

Can you give me an example of when to use asynchronous programming?

Sure! Asynchronous programming is ideal for I/O-bound tasks, like making API calls or reading files, where waiting for a response can be done without blocking the main application.

What about multi-threading? When should I use it?

Multi-threading is best for CPU-bound tasks that require heavy computation, as it can utilize multiple cores to improve performance.

Are there any downsides to using either approach?

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