Kóddokumentáció

Kóddokumentáció, often referred to as code documentation, is the practice of writing explanations and descriptions within source code to help developers understand its purpose, functionality, and usage. This documentation can take various forms, including inline comments, docstrings, and external documentation files. The primary goal of kóddokumentáció is to improve the maintainability, readability, and usability of software projects.

Inline comments are typically used to explain specific lines or small blocks of code, clarifying complex logic or non-obvious operations. Docstrings, on the other hand, are specially formatted comments placed at the beginning of functions, classes, or modules, providing a more comprehensive overview of their purpose, parameters, return values, and any exceptions they might raise. These are often used by automated documentation generators.

Effective kóddokumentáció significantly reduces the time and effort required for new developers to onboard a project and for existing developers to recall or understand specific parts of the codebase. It acts as a communication tool, ensuring that the intent behind the code is clearly conveyed to others, and even to the original author in the future. Poor or absent documentation can lead to misunderstandings, bugs, and increased development costs. Therefore, maintaining up-to-date and accurate kóddokumentáció is considered a crucial aspect of professional software development.
