In this lightning talk at Euruko 2021, Zhi Ren Guoy provides an insightful introduction to adding Byebug to the professional Ruby debugger toolset, emphasizing its role in improving debugging practices.

Key points discussed throughout the presentation include:  
- **Introduction to Byebug**: Byebug is a Ruby debugger gem that enhances the debugging experience for Ruby programs, specifically supporting MRI 2.5 and above. It allows developers to debug without modifying the code.  
- **Transition from traditional debugging**: Guoy highlights the limitations of traditional debugging methods, such as using ‘puts’ statements for tracking execution paths, which can become unwieldy. Byebug offers a more structured approach.  
- **Basic Commands**: A brief overview of essential Byebug commands:  
  - **help**: Displays all available commands.  
  - **list**: Shows the lines of source code surrounding the current execution point.  
  - **break**: Sets breakpoints in the code to pause execution.  
  - **continue**: Resumes execution until reaching the next breakpoint.  
  - **next**: Executes the next line and allows for line-by-line tracking.

- **Conditional Breakpoints**: Byebug supports conditional breakpoints, which allow the debugger to stop execution under certain conditions, improving debugging efficiency.  
- **Variable Inspection and Mutation**: Using Byebug, developers can inspect and change variable values as the program runs, which aids in understanding and correcting errors.  
- **Viewing Variable Scope**: The debugger helps in identifying variable scopes (global, instance, or local) which can clarify issues related to value changes.  
- **Debugging Third-party Gems**: Guoy outlines that Byebug's step command enables developers to investigate issues within third-party gems, which is challenging when using only traditional methods.  
- **Integration with Rails**: Since Rails version 4.2, the Byebug gem is included by default, simplifying initiation of debugging sessions within Rails applications. A simple invocation of the 'byebug' method begins the debugging process at that line.

Throughout the talk, Guoy intersperses humor with practical guidance, making the technical content accessible and engaging. The presentation wraps up with references for further learning about Byebug and debugging practices in Ruby, encouraging attendees to explore the tools discussed.

The main takeaway is that Byebug provides a robust framework for debugging Ruby applications, facilitating error identification and correction far beyond what traditional debugging methods can offer.
