What is the difference between event loop and threading?

What is the difference between event loop and threading?

The event loop is a programming construct that waits for and dispatches events or messages in a program, while threading allows multiple threads to run concurrently, sharing the same memory space.

Can you give me an example of when to use an event loop?

Sure! Event loops are commonly used in asynchronous programming, like in Node.js, where handling multiple I/O operations efficiently is crucial.

What are the advantages of using threading?

Threading can improve performance by allowing multiple operations to run in parallel, making it suitable for CPU-bound tasks.

Are there any downsides to using an event loop?

Yes, one downside is that event loops can lead to performance bottlenecks if a long-running task blocks the loop, preventing other events from being processed.

How do I choose between using an event loop or threading?

It depends on your application's needs: use event loops for I/O-bound tasks and threading for CPU-bound tasks.
