What are some common debugging techniques in Ruby?

Some common debugging techniques in Ruby include using the puts method for simple output, the byebug gem for step-by-step debugging, and leveraging the irb console for interactive testing.

Can you explain how to use the byebug gem?

Sure! To use byebug, first add it to your Gemfile and run bundle install. Then, insert byebug in your code where you want to start debugging. When you run your program, it will pause execution, allowing you to inspect variables and step through your code.

What if I encounter an error? How can I find out what's wrong?

When you encounter an error, check the error message for clues. You can also use begin-rescue blocks to handle exceptions and print out more information about the error.

Are there any tools that can help with debugging in Ruby?

Yes, besides byebug, you can use tools like pry for an enhanced REPL experience, and rubocop for static code analysis to catch potential issues before runtime.
