There are no common standards for measuring code quality. The degree of perfection is a subjective matter. Quality code must be both functional and maintainable. It is often very difficult to combine these two concepts. This is the professionalism of ZORYNEXA S.R.L. – an IT company that can combine what most people cannot and can do it with quality.
The closer the code is to its specifications, the better it is in terms of data model, architecture and structure. At the same time, it must meet the established requirements for performance, memory size, response time. Well-structured code is less prone to errors and unexpected problems. Code that is transferred from one product to another, finalized and even released as open source is high-quality code.
1. Simplicity and readability
Good code is code with an easy-to-understand structure and logic. For developers to be able to maintain other people’s code, it must be easy to read. This feature is important for collaboration and software maintenance. Good code should be as simple as possible, easy to understand. It should use clear names for variables, functions, and classes. Add comments.
2. Scalability and flexibility
Is the code dynamic? Are all values hardcoded? Can a property or style be set, or is it impossible to change anything? Is it possible to scale the code for multiple users? Code scalability is a feature without which it is impossible to expand the workload of the software. Architectural solutions that support horizontal scaling ensure system stability as the number of users increases.
3. Maintainability
Quality code is easy to implement, efficient to run, and easy to maintain. The next programmer should be able to pick up where the previous programmer left off, assuming a similar skill level, and modify or extend the code within the boundaries of the design rules.
4. Testability
Tests simplify the process of finding and fixing errors. Good code is always accompanied by tests that verify its functionality and stability. Good error management increases the reliability of the application and ensures predictable performance in different scenarios.
5. Security
Good, clean code runs without errors or bugs. Even a small error in the code can affect the data. An error in the data affects secondary functionality. Fixing poor quality code without correcting the data already created by the code can increase the number of errors in the data.
To secure the software, several levels of validation are used: front-end, back-end, transmission and database. An effective security system should be integrated into the software design. This is linked to monitoring systems that regularly check for vulnerabilities (malicious code, unauthorized access). The architecture of the software security system is approved at the design stage. Determine the necessary security systems at the design stage of the project architecture.
6. Documentation
Good, high-quality code requires documentation. Codebase documentation is created throughout the project. It helps with integration, code maintenance, and support. Good documentation facilitates team collaboration and keeps the code up to date.
7. Modularity
Quality code is made up of modules and components. Each part of such code performs a specific task. The use of modular architecture and clear interfaces makes it easy to integrate new features. Encapsulation helps isolate code from direct user access for security reasons, preventing data corruption and changes to its properties. This approach saves development time because programmers spend less time looking for external causes and effects when a component needs to be fixed, updated, or removed.
8. Target audience and compatibility
Is the code designed with the target audience in mind? Does it meet the stated needs of the customer? Code that runs successfully on different devices and operating systems increases audience reach and user satisfaction. This is especially true when it comes to platform and device diversity.
9. Reliability
Code can be vulnerable to changes and attacks from external sources. How well does the software react to unexpected events? Reliability is the ability of software to function without errors over a period of time. Good quality code should be stable and secure. Such code implements error handling, error checking, and other security measures.
10. The professionalism of the IT team
Quality should be a priority from the very beginning of development. Only reliable and trustworthy IT companies are able to develop a product “right from the start”, without further torture for the client. To create clean and high-quality code, ZORYNEXA S.R.L. programmers use modern, highly efficient and productive code analyzers that integrate with most programming languages: C, C++, Java, JavaScript, TypeScript, Python, C#, Kotlin, Ruby, HTML and PHP. Static analyzers scan the source code without executing it, not even in the background. This type of inspection most often detects potential problems: compilation errors, unused code, incorrect use of variables and other violations of programming standards.
