I'd wager TS/node/etc going the way of PHP and JQuery in the next decade. SPA will go full WASM (which you could technically use Java for) and non-SPA will be built off better browsers (e.g. WebKit adding nested CSS) and HTMX-style solutions. Note that it doesn't mean everyone will be rolling their own WASM-based engine, but that there will be a bunch of public WASM-based engines (like PyScript/Pyodide stuff) that are tailored for specific domains than one-size-fits-all React.
This leaves "full stack JS" in an awkward middle ground. Sure, you could still use it on your backend (like PHP), but why?
We use JS because there were literally no other practical options, but better browsers and WASM are providing new options.
