The following featured diagrams have been generated from Javascript, one of the most popular programming languages. If your Javascript module/file contains variables, functions and classes - then GitUML will visualise the module/file as a box with the M <<module>> stereotype - global variables and functions in that module are listed as if they were attributes/methods of a class.

Where is gets even more interesting is if your Javascript code has no classes an lots of functions - GitUML can visualise functions as boxes 🤯
- variables become box attributes and inner functions become box methods. How useful - check out the What 'JQuery' looks like diagram. See also:

• The Javascript UML fiddle default example visualises two levels of function nesting.
• Diagram 170 contains a large inner function - visualised as a box, plus some Literate Code Map commentary.
• Diagram 168 visualises ES6 Javascript classes
