There's an defined aproach on documentation?

Hi. I develop in a variety on languages, from C# to Python, mainly for fun (at least python), and although on Java an C# there's a strong concept an mechanism about documentation, on languages such javascripts doesn't.

Then, there's a structured an defined way to make documentation? i mean no the

and other tags, i mean a model, like cascade to software development.

Sorry my english, no native person.
