Wrong. As the article states, MathJax has nothing to do with Markdown. Never did. For that matter, neither did KaTeX. It just inteprets text some grammar parser delivers to it and delivers MathML.

The embrace and extend problem appears when you incorporate LaTeX’s grammar into Markdown.

Perhaps I should say syntax, but really how are you supposed to know what is meant when someone writes $1.50, $2.00 or $\text{more}$.

Besides, nobody gives a crap about Wikipedia file formats. They are not specs that others may implement independently.

GFM is a spec, not a vendor format.

original gruber-swartz markdown has no spec, just perl program with many comical corner cases.

The spec is linked to in the article. Do you know how to click on a link, or do you use Braille?

[flexagoon]

That is an overview of the syntax the program supports. It's not even remotely a formal specification.

[joesuf4]

Yawn.

[applicative]

there is absolutely no specification. one who thinks there is has no idea what such words actually mean. thousands have burned their brains on this question

[joesuf4]

There is absolutely no point to your post. We are discussing GFM, which is also linked to in the article you didn't read.
