I want to create a brand-new programming language, purpose-built for full-stack web development. Think of the expressive ease of Python blended with the modern, modular feel of Kotlin—yet tailored from the ground up for today’s browser and server demands. Here is what I need from you: • A clear language specification that covers syntax, type system, standard library scope, and concurrency model. • A working reference implementation (compiler or interpreter) able to run real code on both client and server. If you choose to compile to JavaScript for the browser and target, say, a lightweight VM or Node.js on the back end, that works for me as long as the developer experience stays seamless. • Core tooling: lexer/parser, REPL, package manager basics, and a minimal set of CLI commands so new users can write, test, and deploy apps quickly. • Starter documentation and example projects that demonstrate a simple single-page application and a RESTful API working together in the same codebase. • Clean, commented source so future contributors can extend the language. I’m open to your preferred stack—LLVM, ANTLR, Rust, Go, or any other toolchain that helps us move fast without sacrificing performance. What matters most is a developer-friendly syntax, predictable error messages, and first-class web features (HTTP, JSON, async I/O) baked in. Show me any previous compilers, transpilers, or DSLs you have built and outline the milestones you’d follow to deliver an MVP we can test in production-like conditions. I’m excited to collaborate closely and iterate quickly until our language feels intuitive, robust, and ready for real projects.
