Hacking F# in JS ecosystem
summary
Claims that F# compiles to real, debuggable JS via Fable — F# to JS and Babel, showing a canvas particle demo and a counter app that both compile, generate source maps, and debug in Chrome. Uses Webpack for bundling and live reload; hot module replacement preserves runtime state when replacing code. Generates TypeScript-style typings from DefinitelyTyped for interop so existing JS/TS libraries work. Targets include browser, Node/Express, Electron, React Native and React VR, and the demos all run successfully.
