What is the difference between threading and processes in Ruby?

What is the difference between threading and processes in Ruby?

In Ruby, threading allows multiple threads to run within the same process, sharing memory. Processes, on the other hand, run independently with their own memory space.

Can you give me an example of when to use threads instead of processes?

Use threads for I/O-bound tasks, like web requests, where waiting for responses is common. Processes are better for CPU-bound tasks, as they can utilize multiple cores.

Are there any limitations to using threads in Ruby?

Yes, Ruby's Global Interpreter Lock (GIL) can limit the performance of threads, especially for CPU-bound tasks, as it allows only one thread to execute Ruby code at a time.

How do I create a thread in Ruby?

You can create a thread using the Thread.new method. For example: Thread.new { puts 'Hello from a thread!' }.

What about error handling in threads?

You can handle errors in threads using begin-rescue blocks within the thread. This way, you can catch exceptions without crashing the main program.
