Changing Software بالعربي | Working Effectively With Legacy Code | Chapter 1

Walking through Working Effectively With Legacy Code by Michael C. Feathers, in each video of the series, we are going to discuss each chapter of the book, pointing out the most important takeaways!
There are four reasons for changing software:
- Adding Feature
- Fixing Bug
- Improving Design
- Optimization
The most challenging thing about changing software is changing behavior and, especially, preserving the existing behavior.
If you need to learn more about design patterns, you can have access to my course, "Ultimate Design Patterns."
This course aims not to just help you master design patterns but also learn to design and build maintainable, extensible, reusable, and robust software, and as a result, help you advance your career level!
