I've been writing JavaScript for 10 years, the majority of that professionally. I have a formal education in computer science. In college, I wrote Java, assembly, C, Python, Lisp, Prolog, and SQL. Outside of school, I've written Go, Rust, Ruby, and probably dabbled in a bunch of others.
As someone that knows programming and that has learned JavaScript, I don't get the sense that people here have actually given JavaScript a fair chance. Sure, it’s not without its issues, but why don't you learn it and see?
Voyager, which I believe is the most popular Lemmy iOS client, is written in JavaScript. It's a fantastic app. There are a bunch of people that love hating on JS, but there are also a bunch of people that hate being locked into cloud services that can be shut down at any time. JavaScript allows you to build local-first apps that are less dependent on a server (obviously, backend is still a thing).
