I don't think that being turing complete means anything in this discussion, because it does not change what the language is for and how its used and interpreted. HTML and CSS are not instructions for the CPU, they are markup languages describing text for humans, not compiling it down to execute machine code for CPUs.
Again, the discussion was about multiline comments, not programming languages.
And regardless of all that, JSX remains one of the most used languages in the world and supports only multiline comments in certain contexts, and JavaScript as a whole uses multiline comments generously.
The discussion was around multiline comments being an anti-pattern, which is entirely untrue. They just serve a different purpose than single-line comments, and usage varies from language to language.
It is an antipattern in Bash. He did not say that for HTML or JavaScript.
Bash doesn't have multiline comments. Even the article acknowledges this lol. From context, it was a general statement, not specific to Bash.
The entire point was having multiline comments in POSIX shell. So that's what we are discussing here right? That's the entire reason we discuss this. Edit: Also as said, this is about programming languages, not markup languages.
