How do different concurrency techniques compare in programming?

Concurrency techniques can vary widely, including threads, async programming, and event-driven models. What specific techniques are you interested in?

I'm curious about threads versus async programming.

Threads allow multiple sequences of operations to run simultaneously, which can be beneficial for CPU-bound tasks. Async programming, on the other hand, is more efficient for I/O-bound tasks as it allows other operations to run while waiting for I/O operations to complete.

What are the pros and cons of each?

Threads can lead to better performance in CPU-bound tasks but may introduce complexity with synchronization. Async programming simplifies handling I/O but can be harder to debug and reason about due to its non-blocking nature.

Which one should I use for a web application?

For a web application, async programming is often preferred due to its efficiency in handling multiple I/O operations, like database queries and API calls.
