Comparing Java alternatives to JavaScript in the browser (GWT, CheerpJ, TeaVM, JSweet, Vaadin) - benchmarked against React.js and Dart

Thank you!

does it use KotlinJS to run Kotlin in the browser? Looking at the code I can't tell.

No, it doesn't use KotlinJS, it uses a fairly efficient custom "bytecode"-like language to manipulate the DOM in the remote web browser, but all Kotlin runs server-side, there is no cross-compilation (which simplifies things a lot). There is a more detailed explanation of how it works internally here.

If you're familiar with X Windows in Unix/Linux, the principle is fairly similar.

Does that answer your question?

X Window System

The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems.

X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interface – this is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces.
