blokkkomentaar

Blokkkomentaar, or block comment, is a type of program commentary that spans multiple lines and is ignored by the compiler or interpreter. It is used to annotate code with explanations, notes, or to temporarily disable a section of code without removing it.

Delimiters for blokkkomentaar vary by language. The most common form in many programming languages is a pair of start and end tokens, such as /* to begin and */ to end a block in languages like C, C++, Java, JavaScript, and CSS. HTML uses different delimiters: <!-- to start and --> to end a block comment. Some languages support alternative or nested forms, and a few treat doc comments specially for automatic documentation generation (for example, /** ... */ in Java).

In practice, blokkkomentaar is useful for longer explanations that would be awkward in a single line, for including licensing or copyright notices, and for temporarily disabling blocks of code during debugging or refactoring. It is important to distinguish between general block comments and documentation comments, which are intended to describe APIs, behavior, or usage and may be processed by documentation tools.

Common considerations include the fact that most languages do not support nesting of block comments; attempting to nest often leads to syntax errors or unintended code behavior. Developers should ensure proper matching of start and end delimiters and avoid leaving outdated or misleading comments in source files. When possible, prefer concise, clear comments and use language-supported doc comments for public APIs to aid maintainability and comprehension.
