What specific skills make a coder “good” at writing clean and maintainable code beyond just understanding algorithms?

Being “good” at writing clean and maintainable code involves a combination of technical skills, software design principles, and professional practices that go beyond just algorithmic knowledge. Here are some key skills and habits that contribute to writing high-quality code:

1. Understanding Software Design Principles

• Separation of Concerns (SoC): Breaking down a system into distinct sections, each addressing a specific concern or feature. For example, separating business logic from UI code.
• Single Responsibility Principle (SRP): Ensuring that a class or module has only one reason to change. This helps keep code focused and easier to modify.
• Open/Closed Principle: Designing code to be open for extension but closed for modification. This allows adding new features without altering existing code.

2. Writing Readable Code

• Meaningful Naming: Using clear, descriptive names for variables, functions, and classes. For example, calculateTotalPrice() is more readable than calc().
• Consistent Formatting: Adhering to a consistent coding style (indentation, spacing…
