What is a rescue block in Ruby?

What is a rescue block in Ruby?

A rescue block in Ruby is used for handling exceptions. It allows you to define code that will run if an error occurs.

Can you give me an example of how to use a rescue block?

Sure! Here's a simple example:

begin
  # code that might raise an exception
  result = 10 / 0
rescue ZeroDivisionError
  puts 'You cannot divide by zero!'
end

What happens if I don't use a rescue block?

If you don't use a rescue block, any unhandled exceptions will cause your program to terminate and display an error message.

Are there different types of exceptions I can rescue?

Yes, you can rescue specific exceptions like ZeroDivisionError, or you can rescue all exceptions using rescue StandardError.
