Nex is a gradually typed, expression-oriented programming language with a TypeScript-first toolchain, bytecode virtual machine, self-hosted .nex pipeline, language server, declarative UI capabilities, and package-management infrastructure. I developed the project as both a programming language and its surrounding developer ecosystem, including parsing and evaluation, optional bytecode execution, self-hosted language components, editor tooling through an LSP extension, a CLI, documentation, and experimental package workflows.
