However, for every explicit rule, there exists an underlying set of unspoken rules that experienced developers follow instinctively. These principles, though rarely mentioned in textbooks or style guides, form the foundation of high-quality, maintainable, and scalable code. Whether you’re just starting out as a novice developer or are already a seasoned expert in the world of software engineering, understanding and embracing these unspoken rules  of coding for both novice and sage developers can significantly elevate your coding skills.

In this article, we will explore several of these essential yet the unspoken rules of coding for both novice and sage developers that span the entire spectrum of coding expertise. These unspoken rules of coding for both novice and sage developers help them to avoid common pitfalls while allowing veteran coders to maintain the elegance, functionality, and longevity of their work.

1. Write Code for Humans, Not Computers

Novices: The Focus on Functionality
When you first start coding, it’s easy to get caught up in the excitement of making things work. You might prioritize getting the program to run, often neglecting the structure or readability of the code. At this stage, it may feel like your code is primarily instructions for the computer, with little regard for how it’s understood by humans. As a result, the code often becomes messy and difficult to follow.

Sages: Code as Communication
In contrast, experienced developers understand that code is not just for the computer; it’s also for the people who will read, maintain, and extend it. Whether you’re writing code for yourself or a team, clarity is key. Clear, concise, and well-organized code is vital because it helps both you and others understand and modify it in the future. Moreover, seasoned developers prioritize readability over complexity, knowing that an elegant, understandable solution will always serve you better in the long run.

Key Takeaway:
Always consider the future readers of your code, ensuring that your logic is easy to understand.

2. Comments Should Explain Why, Not What

Novices: Over-Commenting Code
In the early stages of learning to code, it’s tempting to over-comment, often explaining what each line of code does. This habit may arise from a lack of confidence or the belief that comments are necessary for understanding your code. However, this approach leads to unnecessary clutter, especially when the code itself is already clear.

Sages: Strategic Commenting
Experienced developers know that comments should not explain what the code is doing—if the code is written well, this should be self-evident. Instead, comments should provide context for why certain decisions were made. For example, rather than stating “increment i by 1,” you might write, “We increment i here to track the number of successful attempts,” providing valuable insight into the reasoning behind the decision.

Key Takeaway:
Write clear code to minimize the need for “what” comments and use comments to explain the reasoning behind decisions.

3. Don’t Repeat Yourself (DRY)

Novices: Redundant Code for Convenience
As a beginner, you might often write the same code multiple times, thinking it’s the quickest way to implement a feature. While this may work in the short term, it leads to bloated, error-prone codebases in the long run. Redundancy can quickly become a source of bugs and technical debt as your project grows.

Sages: Refactor and Reuse
Experienced developers embrace the “Don’t Repeat Yourself” (DRY) principle. Instead of repeating logic, they consolidate it into reusable functions, classes, or modules. This makes your codebase easier to maintain and extend. When changes are required, you only need to update the logic in one place, reducing the risk of bugs and inconsistencies.

Key Takeaway:
Refactor and consolidate repeated logic, reusing code through functions and classes to simplify your development process.

4. Learn to Fail Gracefully (Error Handling)

Novices: Ignoring or Hiding Errors
Many new developers struggle with error handling. It’s often tempting to ignore errors, hide them, or let them propagate silently. Unfortunately, this approach can lead to applications that crash unexpectedly or behave incorrectly, leaving users with frustrating experiences.

Sages: Robust Error Handling
Experienced developers know that handling errors gracefully is essential for building robust, user-friendly applications. Rather than merely catching exceptions, they anticipate potential problems and address them proactively. This includes validating user input, providing meaningful error messages, and ensuring that the program fails gracefully when needed, providing useful feedback to the user.

Key Takeaway:
Proactively handle errors to ensure predictable behavior, even in edge cases, and provide clear feedback to users when things go wrong.

5. Test Early and Often

Novices: Delaying Tests
As a beginner, you might view writing tests as an unnecessary burden, preferring to focus on getting features to work first. However, skipping tests at this stage leads to fragile, difficult-to-maintain software. Without tests, debugging becomes more time-consuming as issues arise down the line.

Sages: Testing as a Habit
Experienced developers understand that testing is a vital part of the development process. They write unit tests, integration tests, and end-to-end tests as they go, ensuring that their code works as expected from the outset. Additionally, they integrate tests into their workflow, often using Continuous Integration (CI) to validate each change. This helps catch regressions early, keeping the codebase stable and maintainable.

Key Takeaway:
Write tests early and often, ensuring that your code is reliable and reducing the risk of future issues.

6. Refactor Regularly

Novices: Building and Moving On
As a beginner, you might focus solely on building features and move on once you finish coding a task. Over time, this creates technical debt—code that works but is inefficient, hard to maintain, or difficult to extend. Ignoring refactoring can lead to a tangled, brittle codebase.

Sages: Continuous Improvement
Veteran developers understand that refactoring is not just an occasional task, but an ongoing process. They allocate time for regular refactoring to clean up and improve their codebase, ensuring that it remains flexible, efficient, and maintainable. Even if it feels like a distraction, refactoring helps prevent code from becoming obsolete or overly complex.

Key Takeaway:
Avoid accumulating technical debt by scheduling regular refactoring sessions to keep your codebase healthy.

7. Use Version Control Properly

Novices: Basic Version Control
Many beginners learn the basics of version control (e.g., Git), but may not fully understand advanced techniques like branching, rebasing, or resolving merge conflicts. At this stage, commits are often made sporadically, and repository histories can become disorganized.

Sages: Mastering Version Control
Experienced developers treat version control as an integral part of their workflow. They create feature branches for new tasks, squash commits to maintain a clean history, and write meaningful commit messages that provide context for the changes. Version control becomes not just a tool for backup, but a powerful means of collaboration, rollback, and tracking the evolution of a project.

Key Takeaway:
Master version control by branching often, committing regularly, and writing clear, meaningful commit messages.

8. Know When to Stop Optimizing

Novices: Premature Optimization
Beginners often make the mistake of optimizing everything early on, trying to make their code as efficient as possible right from the start. While optimization is important, premature optimization can lead to wasted effort when it’s not needed.

Sages: Focusing on What Matters
Experienced developers understand that the YAGNI (You Aren’t Gonna Need It) principle is key. They know that building working software is the first priority, and optimization should only come when there’s a clear, measurable need for it. Developers should focus on solving real performance bottlenecks, not speculating about potential inefficiencies.

Key Takeaway:
Focus on delivering working software first and optimize only when performance data justifies it.

9. Understand Your Tools and Ecosystem

Novices: Limited Knowledge of Tools
As a novice, you might stick to the tools and languages you know, without fully exploring their capabilities. This narrow focus may limit your ability to leverage the full potential of your development environment.

Sages: Mastery of Tools
Seasoned developers invest time in learning the full range of tools available to them. They understand how to best leverage libraries, frameworks, and patterns to streamline development. This broad knowledge allows them to make informed decisions when selecting tools and helps avoid reinventing the wheel.

Key Takeaway:
Take the time to learn the full ecosystem around your development tools to make more efficient and informed decisions.

10. Communicate Effectively with Your Team

Novices: Code Alone
As a beginner, you may focus entirely on writing code, often neglecting to communicate with your team or ask for feedback. However, poor communication can lead to misunderstandings and misaligned expectations.

Sages: Collaboration is Key
Experienced developers recognize that coding is rarely a solitary activity. They collaborate regularly through code reviews, stand-ups, and planning sessions. Effective communication ensures that everyone is on the same page, reduces misunderstandings, and fosters knowledge sharing.

Key Takeaway:
Collaboration is just as important as coding. Keep your team informed and seek feedback regularly.

11. Don’t Fear Technical Debt—Manage It

Novices: Avoiding Technical Debt
As a novice, you might view technical debt as something to be avoided at all costs, hoping it will resolve itself or push it aside to focus on delivering features.

Sages: Embrace and Manage Technical Debt
Veteran developers know that technical debt is inevitable and that some debt is acceptable in the short term. The key is to manage it through regular improvements and clean-up, addressing areas of fragility before they become significant problems.

Key Takeaway:
Accept technical debt as a part of development but manage it actively by addressing fragile areas and refactoring when necessary.
