What are some effective tips for debugging Ruby code?
Here are a few tips: 1. Use puts statements to print variable values. 2. Leverage the byebug gem for step-by-step debugging. 3. Check the stack trace for error messages.
How do I use the byebug gem?
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.
Can you explain how to read a stack trace?
Sure! A stack trace shows the sequence of method calls that led to an error. The last line usually indicates the error type, while the preceding lines show the method calls.
What are some common Ruby errors I should know about?
Common Ruby errors include NoMethodError, NameError, and ArgumentError. Each indicates a different issue, like calling a method that doesn't exist or passing the wrong number of arguments.
