What is the difference between concurrency and parallelism in Ruby?

What is the difference between concurrency and parallelism in Ruby?

Concurrency is about dealing with multiple tasks at once, while parallelism is about executing multiple tasks simultaneously.

Can you give me an example of concurrency in Ruby?

Sure! In Ruby, you can use threads to achieve concurrency. For instance, you can run multiple threads to handle different tasks without waiting for each to finish.

And how does parallelism work in Ruby?

Parallelism in Ruby can be achieved using libraries like 'Parallel' or 'Concurrent Ruby', which allow you to run tasks in separate processes.

Which one is better for performance?

It depends on the use case. Concurrency is great for I/O-bound tasks, while parallelism is better for CPU-bound tasks.
