Two Code Reading Paradigms

Developers have different code reading paradigms ranging from understanding every line to focusing only on the current method.
Those wanting to understand everything get frustrated by method extraction, while 'Zen' readers use a stack-like focus on one piece at a time.

INSIGHT

Trust Shapes Code Reading

Trust in code is crucial; lack of trust causes developers to inspect every detail, slowing progress.
Exception handling that swallows errors reduces trust and increases skepticism when reading code.

INSIGHT

Tests Reduce Cognitive Load

Hyper skepticism increases cognitive load and slows down coding due to constant verification.
Small, fast tests reduce cognitive load and enable focused understanding on one code piece at a time.

What does it take to shift from fear to flow when reading and refactoring code? In this episode of the Mob Mentality Show, we dive deep into **"Paradigms of Code Reading"**, exploring the mindsets and techniques that shape how developers approach software understanding. Whether you're navigating legacy code or striving for clean, maintainable designs, this discussion offers actionable insights for individuals, pairs, and mobs alike.

### What You’ll Learn in This Episode:
- **Code Reading Paradigms**: Discover the two ends of the spectrum:
- **Understand Every Line**: Keeping every detail in your head.
- **Extreme Abstraction Zen**: Focusing only on the current module or method.
- **AB Testing in Code Reading**: Insights from live experiments on how pairs and mobs read and understand code.
- **The Role of Trust**: How levels of trust in variable names, methods, and classes influence reading strategies.
- **Overcoming Fear and Skepticism**: What causes developers to ignore method names or distrust the knowledge baked into the code?
- **Cognitive Load and Flow Efficiency**: Learn how reducing cognitive load through small, fast tests can lead to more effective coding sessions.
- **Code Reading Clubs**
- **Coaching Toward Abstraction Zen**: Practical strategies to influence and support others in adopting better reading and refactoring paradigms.
- **Embracing Skeptics**: The value of radical candor, genuine curiosity, and visual aids like diagrams in addressing fear and building trust.

### Key Takeaways:
- Refactoring starts with trust
- Genuine curiosity can replace complaints, transforming how teams collaborate and learn.
- Drawing pictures and visualizing code can unlock new perspectives and improve comprehension.
- Skeptics are not obstacles—they're opportunities for deeper conversations and better design.

Whether you're a seasoned software engineer, a pair programming enthusiast, or new to mob programming, this episode will provide you with practical tools and thought-provoking questions to enhance your coding practice.
