I've used JS/TS since my first year at uni. I've written a lot
of small pages, with either vanilla JS or frameworks in the
frontend (vue, react, solid, astro) & backend (express, nest).
And as far as web goes, I've also used Pug, SASS, Tailwind, CSS-in-JS.
The first PL I've learnt, I've used Java through uni to
implement algorithms, DSAs and backends with Java EE.
Nowadays I'm pivoting towards using Spring and either REST APIs or
dynamic pages with HTMX.
Rust is currently my favorite language. I've used it by myself
for some algorithms, at my last job for a Backend REST API with
rocket.rs, and currently I'm using it in a side project as full stack
language.
I've used C & C++ in uni, to learn about low level programming,
operating systems and Programming Language theory.
I've used C# in uni to learn about videogames, with both Unity &
Godot.
I've used PHP at work, to mantain & update legacy websites, and
to create a REST API along with a React frontend.
