What specifically are you referring to in that table? The original article is a lesson on how to use JavaScript, from scratch, for a beginner. That perfectly fulfills all four requirements in the "tutorial" column:
> oriented to: learning
> must: allow the newcomer to get started
> its form: a lesson
> analogy: teaching a small child how to cook
It does not satify all the requirements of any other column.
1. Tutorials "are lessons that take the reader by the hand through a series of steps." They "are oriented towards learning how."
2. How-to guides "take the reader through steps."
3. "How-to guides are wholly distinct from tutorials."
If I found a "community" around a topic, do I then get to decide what words mean? By consensus, of course.
