What are the best practices for error handling in Ruby?

In Ruby, best practices for error handling include using exceptions, ensuring proper logging, and avoiding rescue blocks that are too broad.

Can you explain how to use the begin-rescue block?

Sure! The begin-rescue block allows you to handle exceptions. You wrap the code that might raise an error in a begin block and handle the error in the rescue block.

What should I do if I want to ensure that some code runs regardless of whether an error occurred?

You can use the ensure block. Code inside ensure will run whether an exception was raised or not, making it perfect for cleanup tasks.

Are there any specific exceptions I should be aware of?

Yes, it's good to be aware of standard exceptions like StandardError, NoMethodError, and ArgumentError. Handling specific exceptions can make your code more robust.
