Ever looked at your old code and wondered what you were thinking? That confusion, frustration, or second-guessing your own logic is something every developer experiences. The good news is, adopting a few simple coding habits can prevent these moments and completely transform how you write and maintain code.
Over the years as a web developer, it has become absolutely clear that great code is not just about solving problems or getting features done. It’s about the habits we develop that shape how sustainable, maintainable, and scalable our code becomes.
In my recent projects, focusing on small but consistent habits has truly transformed my workflow. These habits are not tied to specific languages or frameworks and are foundational practices applicable across the board. If you're aiming to write code that lasts and brings you less frustration down the line, these three habits are essential to master.
For a more detailed guide with deeper insights and examples, check out my full article here: How 3 Small Coding Habits Can Transform Your Workflow and Code Quality
1. Writing Comments That Explain the "Why," Not Just the "What"
Comments often get a bad rap because they are either ignored or misused. But when used wisely, comments become a powerful narrative tool for your code. It’s easy to describe what the code does, but the real value comes from explaining why a solution was chosen.
For example, consider this snippet from a recent project:
// Using debounce to limit API calls during rapid input changes
const debouncedSearch = debounce(handleSearch, 300);
This comment clearly states why debounce is used, preventing future confusion if someone wonders why the API isn’t called instantly.
When you come back to your code weeks or months later, or share it with a teammate, these explanatory comments save precious time and reduce guesswork. They also help during debugging, as understanding the intention behind code makes tracking bugs faster.
2. Refactor Regularly to Avoid Technical Debt
Refactoring is not just a phase reserved for major releases. I learned this the hard way when I ignored small code cleanups, and my project quickly became difficult to manage.
Instead, integrate refactoring as a natural part of your development cycle. After adding a new feature, or while fixing bugs, take a few minutes to tidy up variable names, simplify complex logic, or break down large functions into smaller, reusable ones.
Here’s a quick before-and-after example of refactoring a function for clarity:
Before:
function processData(data) {
// lots of nested if statements and unclear variable names
if (data && data.items) {
for (let i = 0; i < data.items.length; i++) {
if (data.items[i].active) {
// process active items
}
}
}
}
After:
function isActive(item) {
return item.active === true;
}
function processData(data) {
if (!data?.items) return;
const activeItems = data.items.filter(isActive);
activeItems.forEach(item => {
// process active items
});
}
This cleaned-up version makes intent clearer, simplifies logic, and is easier to extend or debug.
3. Consistent Naming - The Unsung Hero
Good names act as hints to the purpose of variables, functions, and classes. I have found that adopting a consistent naming convention, whether camelCase, snake_case, or PascalCase, and sticking to meaningful, descriptive names drastically improves readability.
For example, naming a variable userAge is better than a vague ua, and a function called calculateInvoiceTotal communicates its purpose clearly. When everyone on the team follows the same naming standards, onboarding becomes simpler and collaboration more effective.
Why These Habits Matter Beyond Just Writing Code
Besides making your code cleaner, these habits reduce debugging time and ease peer collaboration. More importantly, they prepare your codebase for growth, making it easier to adapt to new features or requirements without scrambling in chaos.
Software development is a marathon, not a sprint. Writing code that you (or your team) can confidently revisit in six months without headaches is a professional skill worth investing in.
My Personal Takeaway
In my own journey, embracing these habits has changed how I approach challenges. I spend a little more time upfront, but the payoff is smoother development cycles and less last-minute troubleshooting.
When you feel overwhelmed by complexity, try breaking your workflow down to these essentials: meaningful comments, frequent refactoring, and disciplined naming. They form the backbone of sustainable software craftsmanship.

Fantastic insights, Shubhra! Focusing on small coding habits—like clean naming, thoughtful comments, and regular refactoring—truly transforms how we write and maintain code. These tiny, consistent efforts pay off massively in readability, collaboration, and long-term efficiency. Every developer should embrace these habits for sustainable growth!
Thank you so much, Md Mahbubur! 😊 I completely agree. It’s amazing how these small, consistent habits can make such a big difference over time. When we focus on clarity and maintainability, coding becomes more enjoyable and collaborative. Glad it resonated with you!
Two of my habits is to never nest the same block type, and I avoid using else statements. This makes me return early from functions, make use of continue and keep the code more declaritive. I was just recently given a comment from a co-worker:
"First of all, congrats for your work on the SDK. It had been a while since I’d seen such a well structured and clean SDK, congrats"
Thanks for sharing, Chuck! I really like those habits. Returning early and keeping your code clear makes such a difference. And huge congratulations on the praise for your SDK! 🎉 It must feel great to have your hard work recognized.
Thank you for sharing your experience!
I'll keep these in mind.
You’re welcome! 😊 I’m glad you found it helpful. Keeping these habits in mind can really make a difference over time. Happy coding!
I really appreciate your generosity of sharing your experience.
It reminds me of my first day off coding.
Thank you so much, Abdoulie! 😊 I’m glad it resonated with you. It’s amazing how those first days off coding can leave a lasting impression. Hope your journey continues to be full of growth and enjoyable moments!
