Remember – there’s no one good solution for everyone. For instance, the Model-View-Controller is a common choice in web development because it’s a great way to organize your code. Code can’t be a complex riddle that only its author can solve. Some say that clean code is the one that doesn’t stand out, and it actually should be a bit boring.
These things change from language to language and there is no universal standard. Use your IDE’s refactoring features and extract a method whenever you come across a repeated code segment. You can change the name of the function to something like checkPasswordAndInitializeSession to https://globalcloudteam.com/ make this effect explicit. But when you do that, you should notice that your function is actually doing two things and you should not initialize the session here. The key point is, they promised to do another thing and you need to read the code carefully to notice the side-effect.
Code with poor naming conventions, such as variables with short, non-descriptive names, or functions with names that do not accurately reflect their purpose. Ali explained that she doesn’t use all of these principles all the time. But they can still be helpful guidelines to help write code that others can read and change down the road.
If your changes won’t be common, then write your rules in a way to affect only a certain element and nothing else. This will allow you to find and modify the main parent element easily in one place when making changes in future. Atomic classes are simple, single-purpose units of styling.
KISS: Keep It Simple Stupid.
If a project doesn’t meet these high standards, it won’t pass the quality gate, and is therefore not ready to be released. Nevertheless, our Incora team hopes that these tips were helpful and you will strive to write clean and maintainable code. We would be glad to use such methodologies in the development of your idea. Even though sometimes it is tempting to cut corners, we should not ignore best practices.
This benefits you by elevating your code quality — when you can discuss your code clearly, you can more effectively ask for help and suggestions on how to improve what you write. Clean code won’t write itself, it takes dedicated focus on putting forward what you mean to convey. Strive to write self-documenting code, clean and structured code that doesn’t need comments all over to explain what it’s doing. Using whitespace can be incredibly powerful and normally has absolutely no downside.
While in this function, whitespaces and indentation are properly taken care of. In this function, whitespaces and indentation are not taken care of.

Complexity metrics Complexity is often measured using the cyclomatic complexity metric.
Bootstrap relies on the variables.scss file, which allows you to easily configure and customize your front-end without writing a single line of code. I — The interface segregation principle states that you shouldn’t add additional functionality to an existing interface by adding new methods. Instead, create a new interface and let your class implement multiple interfaces if necessary. It is also common when sloppy developers name a function the same way in different files. While creating a file or directory, we have to check the naming convention. If there are too many, rename it or create a subdirectory.
The names of classes should look like .noun-adjective. For more information on quality gates and to make sure your quality gate is enforcing your standards, check out theQuality gates page. The New code definition can be set at different levels . Depending on the level at which your new code definition is set, you can change the starting point to fit your situation.
Why do we need to care about Clean Code?
However, this must not hinder the intentions of the code. Comments might also include legal comments, how to write cleaner code in C# documentations, or to-do lists. Programmers use comments to express themselves in the code.
It includes many new classes which will help you create layouts faster, especially Flexbox and spacers. \n\nTry to look for existing CSS rules and variables before writing new ones. \n\nIf you need to use the same block but with different styling, try to keep the HTML as untouched as possible. Just add one class to the parent element and apply all new stylings to the children of that class in CSS. I hope you have been able to take away something helpful and that you will think more about writing minimal HTML and CSS code with best practices.
KISS (Keep it simple, stupid)
Group like items in your code so that it is more reusable. What is clean code exactly, and what should it look like? To put it simply, it is a codebase that is clear enough for the rest of your team. Recently, X-Teamers discussed their most important principles to keep their code clean, and we decided to share the best ones with the world.
Each entity that we operate during the development should be responsible only for its own part of the functionality. FinTech Are you building a neobank, trying to implement the right payment system, or launching any other financial product? EWalletBankingEdTech The global education technology market size is expected to reach USD 318.8 billion by the year 2027. Third, by creating code that isunderstandable, we reduce the amount of time necessary to comprehend what needs to be done in order to extend, modify, or fix the software. Understandable code also reduces costs incurred by mistakes, bugs, and miscommunications caused by misunderstanding the intent of the code. Clean coding is not a skill that can be acquired overnight.

I encourage you to go one step further and learn how to write clean code yourself. Finally once you’ve developed this craft, please become an advocate and teacher of clean-coding practices to your peers. And because people need to understand the code we write, we can say that the code we write is not intended only for the computer but also for humans. Clean code is clear, understandable, and maintainable. When you write clean code, you’re keeping in mind the other people who may read and interpret your code at a later time.
- The code that is less prone to errors and easily readable, modifiable, scalable, maintainable by any developer is referred to as « Clean Code ».
- You can use pull request analysis and pull request decoration to make sure that your code meets your standards before merging.
- Together with Geniusee specialists, we created an article with the best practices of Mobile Banking Security 2022.
- Using em and px units gives us flexibility in our designs and the ability to scale elements up and down instead of being stuck with fixed sizes.
- This is much better because MAX_CLASSES_PER_STUDENT can be used in many places in code.
- There’s no single recipe you can follow to write good, clean code.
Growth is a problem in the software industry, because there are too few people with experience to mentor the new engineers. The number of people in our industry doubles every five years. This means half the programmers in the world have less than five years of experience. A good engineering manager can see this division in the team. Then maybe you can divide the team and give one half tasks where they’re not going to do harm, and keep the other part of the team focused on the project.
Another important principle of clean code is simplicity, which means that code should be as simple as possible, without unnecessary complexity. To achieve this, developers should avoid using complex data structures or algorithms unless they are necessary, and should avoid adding unnecessary features or functionality. Bad code is difficult to understand, more complex than it should be, not easy to test, and it makes other developers seethe with frustration. While it might take longer to write clean code in the short term, it’s beyond established that writing clean code will save everyone time, effort, and ultimately money. It states that most systems should be kept as simple as possible . The question to ask when you’re writing code is “can this be written in a simpler way?
How to Write Functions
Also, it is great when the code is well-documented or even self-documented. To elevate code quality and maintainability, you can use a variety of practices including refactoring, and unit and acceptance tests. It is a great practice to apply the DRY principle because it saves much time in development. The modification of an element doesn’t require a change in any other logically unrelated elements in a system. With this principle, you minimize the amount of unnecessary work, which is crucial for the developer’s productivity and software simplicity.
Refactoring techniques will help you simplify your code, get rid of duplications and make it less ambiguous. The first one is the example of messy code which doesn’t carry logical meaning. The second example is more clear, as it names exactly what is the unit to measure. You should always use pronounceable names; otherwise, you’ll have a hard time explaining your algorithms out loud.
Coding ConventionsIt is important to have a list of coding conventions. But before you start making the list, everyone on the team must understand the significance of this agreement. Do not expect such an agreement to be adopted the first time, there will be a lot of discussions. With the right design and architecture, extending your code can be done without much time and expense. The entities of the code should not be closely related to each other; the code should be somewhat abstract and self-sufficient.
Reasons Why Clean Code Matters
Clean code can differentiate you from other programmers. The details added here are generally specific to the implementation. The details added here are generally implementation free and focus mostly on the specification purposes.
It’s especially difficult to achieve when your teammates have different workflow and coding preferences. Then, writing clean code that is minimalistic and easy to understand by others requires some time and effort. Well, there are a lot of benefits of writing clean code for your team and the whole project that makes it worth trying.
Otherwise, if you are going to manually write all the customizations on your own, you’d be better not to use a framework at all. Clean code is code which is easy to read and understand as well as easy for any developer to maintain and modify. It means that assigned names are meaningful but not too long. No parts of code should be repeated, and almost everything should be consistent.
