summary
Shows a concrete pipeline that starts with text and ends as runnable JavaScript, claiming a full compiler from lambda script to JavaScript implemented in F sharp. Covers tokenizer bugs, lexer/token rules, bottom‑up parser building a CST then an AST, type ideas and unit tests, and codegen using escodegen with HJs interop. Demo compiles and runs printing true/false; transcript also mentions preventing six million tons of co2.
