| :::info Why regex can't parse HTML | ||
|
|

| While [Bobince's infamous StackOverflow answer](https://stackoverflow.com/a/1732454/325365) is funny, it doesn't go much into explaining. In formal language theory, HTML's hierarchical and nested structure makes it a [context-free language](https://en.wikipedia.org/wiki/Context-free_language). Regular expressions match patterns in [regular languages](https://en.wikipedia.org/wiki/Regular_language), which are much simpler. This difference makes it hard for a regex to handle HTML's nested tags. HTML's complex syntax rules and various edge cases also add to the difficulty. |

wouldn't ```bash make more sense? (I guess that is just a nit )

I use ```text consistently throughout both of the courses, because setting it as bash oftentimes than not highlights words which I don't need colored, especially in the output of the commands. Usually, there's like one line of bash and the rest is the output, so I opted for setting it as text, because the result is visually less confusing, imho.

I think ```bash would be great for actual bash scripts, bash functions, etc.
