Why is Tailwind written in JavaScript and not something else?

[Martleby]

I was looking through the various issues, discussions, problems, questions and answers about Tailwind and a lot of them all seem to be about build issues, problem with the myriad of bundlers, packagers, node versions, and various of the other dependencies, incompatibilities, and gotchas involved with anything to do with modern JS.

It must be a nightmare dealing with that complexity, especially since at its heart Tailwind embraces simplicity in its approach to css.

So this made me wonder why it's all written in JS. Why not avoid it entirely and use a different language?

I had to install Node for things to work, so I wouldn't object to installing a Tailwind specific compiler. In my app I've removed all css stuff from Laravel mix and instead use the Tailwind cli tools.

I guess my question is: Why can't Tailwind "be" a tool for the web without "being" written in tools for the web?
