Using JS/Node and React/Native, you can target absolutely every platform with a unified codebase. There's essentially no technical debt in choosing these technologies because if you start with a web app and then want to make a "desktop app", there's Electron. Want to make a mobile app? React Native. There's even React Native for Windows and macOS for a more true desktop app with a native UI. You can also run your JS on the backend with Node, and even inside the database (PL-V8 runs V8 for stored procedures inside PostgreSQL, aside from obviously CouchDB or MongoDB and others). Heck, you can even write an app for the Xbox or build out on several IOT platforms using JavaScript! Is there any reason to create the same thing in 4+ different languages? Are you going to rewrite your frontend in C#, Kotlin, and Swift? Are you going to deal with different language models and incompatibilities? Rewriting the same exact functions over and over, and unit tests for every single one, keeping in mind the subtle semantic/scope differences between each language--and then realize you still have to serialize/deserialize to JSON to talk to your backend and other services and just juggle JS data models between all these languages and ecosystems. Choosing JavaScript and React today are the sensible default where you won't code yourself into a corner, is what I'm getting at. And you can also now choose TypeScript or ClojureScript in all such cases as well.
