__doc__ (docstring)

Docstring is a string literal specified in source code that is used, like a comment, to document a specific segment of code.

A docstring occurs as the first statement in a module, function, class, or method definition.

Languages that support docstrings include Python, Lisp, Elixir, and Clojure.

Docstrings can be accessed by the __doc__ property on functions. The following JavaScript example shows the declaration of docstrings within a source file:

};

console.log(test.__doc__);  // @params {string} data

Preserve directives

/** @preserve */ — [Google Closure Compiler] (https://developers.google.com/closure/compiler/docs/js-for-compiler) /*! .. */ — [UglifyJS] (http://lisperator.net/uglifyjs/)

This annotation allows important notices (such as legal licenses or copyright text) to survive compilation unchanged. Line breaks are preserved
