Why learn about coding habits? Professional developers don’t just write good code. They also develop strong habits that save time, reduce frustration, and improve debugging.
Helpful Coding Habits:
- Practice Often: The key to learning programming is consistent practice.
- Learn by Doing: Coding is something you need to do in order to learn.
- Break Big Problems Into Small Problems: Identify smaller components that tackle one at a time
- Make One Change, Then Test It: Make one small change, run it, test it, fix it, save it, repeat
- Write Code for People, Not Just Computers: Software development is often a team sport – if you are working with others, they will need to understand your logic and build upon it.
- Protect Your Progress:
- Saving protects your current changes
- Version control preserves meaningful states and lets you track or restore changes
- Backing up protects against losing files or even an entire repository
- Learn How to Get Unstuck
- Learn and Use Keyboard Shortcuts
Practice Often & Learn by Doing
Every great programmer started as a beginner.
The key to learning how to code isn’t memorizing everything, it’s practicing consistently.
Think of coding like learning a musical instrument or a new language. The more you practice, the more natural it becomes. Write code often, solve small programming challenges, and build simple projects. Each program you create strengthens your skills and boosts your confidence. Don’t be discouraged by mistakes or bugs; they’re a normal part of the learning process. Every problem you solve teaches you something new and helps you become a better programmer. Practice good coding habits so they become natural and second nature.
Coding also develops valuable skills like problem-solving, logical thinking, and creativity. These abilities are useful not only in software development but in many careers and everyday situations. As you grow, focus on mastering the fundamentals, including data types, data structures, and algorithms. These core concepts form the foundation of programming and will make learning new languages and technologies much easier.
Keep practicing, stay curious, and celebrate your progress. Every line of code you write brings you one step closer to becoming a confident programmer.
Break Big Problems Into Small Problems
Computational thinking is a powerful way to solve problems. One of the key computational thinking concepts is decomposition, which takes complex challenges and turns them into simple, manageable steps – an essential skill for every programmer.
Make One Change, Then Test It
Start small and test often. When you’re writing code, resist the temptation to build several new features before checking whether your program still works. Instead, make one small change at a time, test it, and fix any problems before moving on.
- Add code that does one simple task. Focus on a single feature, function, or improvement rather than several at once.
- Run your program and test the change. Check that the new code works as expected and that it hasn’t broken anything that was already working.
- Fix any bugs immediately. If something isn’t working, it’s much easier to find the cause when you’ve only changed a small amount of code.
- Save or commit your work. Once everything is working, save your progress. If you’re using version control, make a commit with a clear message describing what you changed.
- Repeat the process. Continue building your program one small step at a time.
This incremental approach makes debugging easier, reduces frustration, and helps you make steady progress. Because each change is small, you always know what was modified most recently, making it much quicker to identify and fix problems if they arise. It also helps you build confidence that your program is working correctly as it grows.
Write Code for People, Not Just Computers
Good code isn’t just code that works. It’s code that’s easy to read, understand, and maintain. As you learn to program, writing clear code will help both you and others understand what your programs do. One of the strongest coding habits is to write code that you and others can easily understand and follow.
Clear names make your code almost read like a story. Choose meaningful names for your variables, functions, files, and projects. Names like totalScore or calculateAverage() are much easier to understand than x, temp, or func1.
Think of each project as a learning journal that captures your progress. When you’re just starting out, don’t be afraid to write comments. Use them to explain your thinking, record what you’ve learned, or remind yourself why you solved a problem a certain way. As your skills grow, you’ll rely less on comments and more on self-documenting code; code that explains itself through clear names, thoughtful organization, and simple, readable logic. The goal isn’t to write more code. It’s to write code that’s easier to understand.
Focus on making your code a little clearer each time you practice. Remember, every experienced programmer writes code that can be improved. Small improvements add up, and before long you’ll be creating code projects that are not only correct, but also clean, readable, and enjoyable to work with.
Code is written for computers to execute, but also for humans to understand.
Protect Your Progress
Get into the habit of saving whenever you finish a meaningful change. One of the simplest habits you can develop as a programmer is to save your work often. There’s nothing more frustrating than losing your progress because of a power outage, computer crash, or accidental mistake. Using keyboard shortcuts like Ctrl + S (Windows/Linux) or ⌘ + S (Mac) makes saving quick, easy, and automatic. Before long, it will become second nature.
Use version control to create a safety net of working versions. If a new change introduces a problem, you can quickly revert back to a previous stable state.
Backups protect your hard work and give you peace of mind if something unexpected happens. It’s also a good idea to keep more than one copy of your work. Store important projects in multiple locations, such as your computer, a cloud storage service, or an external drive. Saving your work regularly and keeping reliable backups are small steps that can save you hours of frustration and help you build confidence as a programmer.
- Save protects your current changes.
- Version control preserves meaningful states and lets you track or restore changes.
- Backup protects against losing the files/repository itself.
Learn How to Get Unstuck
Asking someone for the answer may get you past the current challenge, but you might be more successful if you practice a habit of problem-solving that included checking your mental model of what you thought would happen against what actually did happen.
It also helps to identify a specific problem, instead of asking for help with something larger and vaguer. For example, “My game doesn’t save player progress to the hard drive” is harder to help troubleshoot than, “I’m getting an error that the file for player progress can’t be found”.
Example:
- Read the error.
- Identify what you expected to happen.
- Identify what actually happened.
- Try to isolate the smallest part that isn’t working.
- Then ask for help with that specific problem.
Learn and Use Keyboard Shortcuts
Learn common keyboard shortcuts so you can perform routine tasks more quickly.
- Ctrl+C / Cmd+C: Copy the selected item.
- Ctrl+X / Cmd+X: Cut the selected item.
- Ctrl+V / Cmd+V: Paste the item that was copied or cut.
- Ctrl+Z / Cmd+Z: Undo the previous action.
- Ctrl+Y / Cmd+Shift+Z: Redo the action that was undone.
- Ctrl+A / Cmd+A: Select all content.
- Alt+Tab / Cmd+Tab: Switch between open applications.
- Ctrl+S / Cmd+S: Save the current document.
