# Comments --- ## Summary --- - [Why should I use comments](#why-should-i-use-comments) - [Single-line comments](#single-line-comments) - [Multi-line comments](#multi-line-comments) ## Why should I use comments --- A comment is some text that is completely ignored by the compiler. This means that you can write everything in it. Using comments is very useful when your project is growing, or if you work with other people, to give explanations about what a function does, why you did use an algorithm instead of another one, or to have a reminder. ## Single-line comments --- Single-line comments do end at the **end of the line**. ```sd // some text // which continues // on the other lines and here you get an error ``` ## Multi-line comments --- Multi-line comments are delimited by `/*` and `*/`. ```sd /* some text which continues on the other lines */ ```
