Code Cleanliness and Quality

There are no common standards for measuring code quality. The degree of perfection is a subjective matter. Quality code must be both functional and easy to maintain. It is often very difficult to combine these two concepts. This is the professionalism of Emat EOOD - an IT company that can combine what most people cannot, and do it with quality.

The closer the code is to its specification, the better it is in terms of model, architecture and data structure. At the same time, it must meet the stated requirements for performance, memory size, response time. Well-structured code is less prone to errors and unexpected problems. Code that is transferred from product to product, completed and even released as open source is high quality code.

1. Simplicity and readability
Good code is code with an understandable structure and logic. For developers to maintain other people's code, it must be easy to read. This characteristic 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 hard-coded? Can a property or style be set, or is it impossible to change anything? Is it possible to scale the code for more users? Code scalability is a feature without which it is impossible to expand the software workload. 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 design rules.

4. testability
Tests simplify the process of finding and fixing bugs. Good code is always accompanied by tests that verify its functionality and stability. Good error handling increases the reliability of the application and ensures predictable performance in different scenarios.

5. Security
Good, clean code runs without bugs or errors. Even a small bug in the code can affect the data. A bug in the data affects secondary functionality. Fixing poor quality code without fixing the data already created by the code can increase data errors.

Several levels of validation are used to secure software: front-end, back-end, transmission and database. An effective security system should be built into the software design. It is linked to monitoring systems that regularly check for vulnerabilities (malicious code, unauthorised access). The architecture of the software security system is approved at the design stage. Determine the required security systems at the design stage of the project architecture.

6. Documentation
Good, high quality code requires documentation. Documentation of the code base is created throughout the project. It helps with onboarding, 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. Using modular architecture and clear interfaces makes it easier to integrate new features. Encapsulation helps to isolate code from direct user access for security purposes, preventing data corruption and changes to its properties. This approach saves development time because programmers spend less time looking for external cause and effect 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 customer's stated needs? Code that runs successfully across devices and operating systems increases audience reach and user satisfaction. This is especially true with the diversity of platforms and devices.

9. Reliability
Code may be vulnerable to tampering and attack from outside sources. How well does the software react to unexpected events? Reliability is the ability of software to function without failure 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. 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 the first time" without further torture for the customer. To create clean and high quality code, Emat programmers use highly efficient and productive modern code analysers that integrate with most programming languages: C, C++, Java, JavaScript, TypeScript, Python, C#, Kotlin, Ruby, HTML and PHP. Static analysers scan the source code without executing it, 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.
