What are the best practices for handling exceptions in Ruby?

In Ruby, it's important to use begin-rescue blocks to handle exceptions gracefully. You should also avoid rescuing from StandardError unless necessary.

Can you give me an example of a begin-rescue block?

Sure! Here's a simple example:

begin
  # code that may raise an exception
rescue StandardError => e
  puts "An error occurred: \\#{e.message}"
end

What should I do if I want to log the error?

You can log the error inside the rescue block. For example:

rescue StandardError => e
  logger.error("An error occurred: \\#{e.message}")
end

Are there any exceptions I should avoid rescuing?

Yes, you should avoid rescuing from SystemExit, NoMemoryError, and other critical exceptions that indicate serious issues.
