# Comments Comments can be used to document code. A comment is text that is not executed. *Single-line comments* start with two slashes (`//`). These comments can go on a line by themselves or they can go directly after a line of code. ``` // This is a comment on a single line. // Another comment line that is not executed. let x = 1 // Here is another comment after a line of code. ``` *Multi-line comments* start with a slash and an asterisk (`/*`) and end with an asterisk and a slash (`*/`): ``` /* This is a comment which spans multiple lines. */ ``` Comments may be nested. ``` /* /* this */ is a valid comment */ ``` Multi-line comments are balanced. ``` /* this is a // comment up to here */ this is not part of the comment */ ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://max-daunarovich.gitbook.io/flow-network/introduction/comments.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
