> And where are the equivalent libraries for Go, Rust and Java? Not aware of anything yet for Go/Rust, but Java and Python have had libs like this for a while now (to the point that Pyjamas hasn't been updated in a decade): * GWT (Java) * Pyjamas (Python) * Vaadin (Java) Those are general purpose. After that you have the sci/data-oriented python frameworks like dash, streamlit, etc.
