No, sad to say, I don't code on steem and I learned only some basics of react. However, I'm pretty familiar with JavaScript and other scripting languages. At the moment I primarily work on making all kinds of automations, mostly written in AppleScript and Swift (also VBA automations), but this is of no use here :(
I'm a fast learner though and I already have React and React Native on my wish list (to learn as my new items of my Swiss army knife). Hmmm, when I finish my ongoing projects, I may start with React...
