Even if it is functional, software code might be of low quality based on several factors. It’s like having an issue with a vehicle. It seems to be progressing, but it is continuously in need of maintenance and may refuse to start at any time.
Terrible code is akin to a bad book. It’s disorganized, has a messy framework, and it’s typically tough to figure out what the author is trying to express.

The Most Telltale Signs of Bad Code
If we attempt to come up with a list of symptoms of low-quality code, we’ll come up with the following:
It’s difficult to understand; it includes needless iterations and complications; the function name isn’t clear enough to indicate the job it handles;
Code may become dysfunctional if it is not supplemented with something.
As a result, just because software works doesn’t always indicate it’s written well. The scent of code is a symptom, not the cause.
How Does Bad Code Endanger Your Project?
Outsiders may not see it as a huge concern, and bad code may not seem to be a huge concern. After all, it’s all about the operational software. On the other hand, bad code causes many issues, particularly in the long run. The following are the reasons:
Making changes to low-quality software code takes a lot of time (and money), and the cost will only rise over time; adding new functionalities is difficult or impossible; your code is unpredictable; you never know what will break and when; the need to work on such a project lowers developers’ motivation.
Consequently, the development pace slows, deadlines are prolonged, and future changes are more expensive. Bad programming may derail the project if all of this is important to the product’s target audience or owner.
Why Is Good Code Necessary?
Even though the compiler executes every computer program, software code is created by humans, and this is because high-level programming languages have human-friendly syntax and instructions.
This development method lays high demands on code quality, particularly readability and comprehensibility.
Good code is simple to understand, according to the guiding idea. It is the most crucial factor. Good code is when a new person reads and understands it completely.
The benefits of having a clean code are self-evident. It enables you to:
- Any employee to grasp a novel project; team members to interact effectively with one another; developers to make minor changes without difficulty;
- Rebuilding a project fast to satisfy a customer’s new needs; carefully incorporating new technology to ensure that everything continues to operate.
It is necessary to examine excellent code to understand its essential operating principles. To put it another way, you can hardly call your code excellent if only an advanced or genius developer can understand it. It is fantastic if any junior can quickly grasp code.
Best Practices for Developers: 9 Principles of Writing Good Code
Now that you understand what excellent code is, you must figure out how to create it. Here are some guidelines to follow to get the desired outcome:
Stick to the code guidelines.
One of the most basic and crucial ideas is to agree in advance with your colleagues on systemizing your code and operating in certain scenarios. Then, code produced by various programmers will seem comparable, and you’ll have no trouble working with someone else’s code or vice versa. Furthermore, each programming language has its own set of coding conventions.
You should refactor your code.
This method involves reorganizing software code without altering its behavior. To begin, you’re working on a creative project: you’re writing code to make the program operate. Then you “tidy up,” making your code tidy and bringing it to the desired shape. Read on to learn more about code refactoring in programming.
Conduct a code audit.
This approach enables developers to review and offer comments on each other’s code. This method aids programmers in avoiding blunders and ill-advised changes. Furthermore (and this is critical), team members get a sense of what other developers are working on, which helps them avoid duplicating functions.
If it’s not essential, don’t enlarge your code.
It doesn’t imply your code is excellent just because it has a lot of lines. Developing software aims to address a specific issue rather than write as many words as feasible. The simpler it is to work with, the fewer lines of code you write to address a certain issue.
Make a comment on the software code you’ve written.
This guideline is particularly crucial for new developers or when writing high-volume software that you will need to deal with again and again in the future. You risk misinterpreting your code if you leave it without even a single remark.
Never, ever, ever, ever,
This method will always assist you in creating and sustaining a software product since finding and fixing issues will take much less time. You will save a lot of time looking for faulty code blocks using a log file.
Ensure simple coverage and debugging of unit tests.
The technique of testing software units is known as unit test coverage. You can use unit tests to check if you change your code. When creating a software product, an engineer should think about testing from the start.
Consistency is key.
Carry out comparable tasks in the same manner. Consider utilizing a similar name, a similar sequence of arguments, and a similar body structure if you create a functionally similar method to one that already exists.
Make the process of making further changes easier.
The simpler it is to tweak code, add new attributes, increase speed, and change the structure’s design, the better it is optimized.
It is possible to enhance your code in other ways (for instance, pair programming). When developing code, though, you might get the greatest results by mixing different techniques.
As you can see, developers can follow some guidelines to ensure their code meets “good.” Furthermore, the more sophisticated and large-scale the project, the more important code quality becomes, since testing and correcting problems may be expensive.
Developers that follow best practices, adhere to standards, do frequent testing, and consider comments from their peers may be certain that they will offer the greatest outcomes.
