apiDoc VS docco

Compared to the first three tools, apiDoc takes a different approach towards generating documentation. Rather than rely on an API definition file like OAS, apiDoc is a package that allows you to add documentation directly into your source code through annotations. While there are third-party libraries that can create OAS files based on code annotations, having this built-in makes apiDoc slightly better if you want to control documentation through code instead of having a separate tool.

API Link - apiDOC

apidoc is a node plugin that can be installed in the node application. This plugin helps to write and generate REST API documents for node.js applications.

i have seen those in annotated javascript documentation. but it was the other way around. (comment on the left, and code on the right).

they all seem to use docco[0] with the option to display comment in "parallel". the author of docco used it in their library underscore[1].

Side note - it's been a while since i've seen a Docco-style annotated-source-style documentation! http://ashkenas.com/docco/

Backbone.js was the first time i saw it, and I loved it! https://backbonejs.org/docs/backbone.html It demonstrated to me that the libraries I use are just normal code that other people write, and i myself can read it to understand a problem.
