How do I compile C++ to JavaScript in a browser?

Question

I\'m aware of Emscripten and LLVM, but neither are written in JavaScript intended for a browser.

As far as I can tell, the tools exist, but they haven\'t been put togeth

Answer 1

In theory, it may be possible to develop a self-hosting version of Emscripten that runs in a browser, though this hasn't been done yet.

Alternatively, it is possible to run a C++ compiler (or even an entire operating system) using an x86 emulator in JavaScript.
