Embracing Black Magic: The Power of Code Transpilation
summary
Claim: source-to-source transformers rewrite code by operating on the AST and can be composed as visitors to do real runtime things. Examples show using Babel and TypeScript and the CoffeeScript compiler; a sandbox demo transpiles every expression into a validate call and throws on forbidden strings, and an instrumenting demo injects line-dispatch calls to visualize and pause execution. Source maps are used to map back, and generators/parsers like Babylon are the actual tools that make it work.
