JSX is the one contribution to my overall development experience over the last few years, I have used JSX / TSX in Vue.js and really preferred it over SFCs for a good long while.
Then I picked up lit-html and saw another more natural way to write templates, but then google kind of merged the project with lit-element. It's okay... But lit-element added a ton of boilerplate on top of the simple templating language I was attracted to, mostly declaratively defined OOP which I will tolerate but not enjoy.
Finally I finished my trip to obscurity with another JSX powered beast, Stencil - a way of writing web components that is so good, for two years, I couldn't bring myself to learn React, and not stand out. Stencil like Svelte is a compiler and scores incredibly well in performance out of the box, 100 performances, yes please! It also manages to do SSR with web components, yeah, no idea how 🧙♂️, today I'm not going to learn about that.
React is kind of the jQuery of today (in it's popularity and future tech debt hangover), so everyone must know it, which sucks for me because I could pick up React projects which I often do, but am I a React expert? Kinda, sorts, no.. so no CV entry 😅
But React functional components, they look nice, and all the libraries I personally will never finish in order to get to my end goal, well they already exist In React... So today with great caution, I am going to try and get React on my CV, like everyone else, I'm so mainstream.
