# Syntax 101

Only way to understand that syntax, actually.

**JM-**'s Syntax is characterized by the facts that it *mixes* 2 programming languages:\
**C** and **C++** and is also [*edgy af*](https://www.urbandictionary.com/define.php?term=edgy).

### The Incest Rule

The Incest Rule is a principle of **JM-**'s Syntax that reads:

*"Every function has the ability of using and creating other functions inside of its body to achieve its goal."*&#x20;

So technically speaking you could `#def`ine an empty function and use it as\
C-like languages' `main()`.\
**\*Important sidenote**: This *kinda* issue has been addressed in the [PIDD](/jmdash-docs/design-documents/the-post-idd.md).

### Important note

All of the informations regarding JM-'s Syntax that you will find in this documentation are based on the Initial Design Documents: [IDD](/jmdash-docs/design-documents/initdesidocu.md), [IDoLD](/jmdash-docs/design-documents/initial-design-of-libraries-document.md), [IDoEHD](/jmdash-docs/design-documents/initial-design-of-error-handling-document.md) and every other [Design Document](/jmdash-docs/design-documents/initdesidocu.md) like the [PIDD](/jmdash-docs/design-documents/the-post-idd.md) and their [revis](/jmdash-docs/design-documents/the-pidds-first-revision.md)[ions](/jmdash-docs/design-documents/the-pidds-second-revision.md)
