This article mentions inflection points, but doesn’t delve into clientside apps significantly (e.g. SPAs). How far away are we from transitioning from component based JavaScript frameworks like react, to something which compiles to wasm?
But if you want to use a front end framework that compiles to warm then you can do that today. Rust, Go, C# and more all have libraries (only Rust really makes sense though, as the others involve shipping a huge runtime). Just don’t expect it to be any faster than JS.
On the web, Wasm has currently found the most success with compute-intensive applications, since the JS <-> Wasm bridge is still pretty expensive. There are already some Wasm-based frameworks like https://platform.uno/ that work on the web, but things like React/React-native and Flutter have a huge head start.
Edit: I guess you mean you’d compile your React app to Wasm, no?
More clearly: once Wasm interactions with the browser are fast, a new framework + Wasm could replace React + JS.
