JavaScriptiin

JavaScriptiin is a hypothetical programming language envisioned as an evolution of JavaScript, intended to preserve familiar syntax while adding features aimed at reliability and scalability. It is described as a gradually adoptable language that can interoperate with existing JavaScript code.

Design goals include optional static typing, a clearer module system, and stronger tooling. The language aims to compile to plain JavaScript for broad compatibility or to WebAssembly for performance-critical code, enabling deployment in browsers, Node.js, and standalone runtimes.

Syntax and typing: JavaScriptiin supports optional type annotations and type inference. Programmers can write code with or without types, using constructs such as interfaces, generics, and structural typing. Objects retain their dynamic roots, while typed code can be statically checked by the compiler.

Modules and tooling: It uses a module system compatible with ES modules, with import and export, and a compiler or transpiler that emits JavaScript or WebAssembly. Tooling includes an optional type checker, auto-completion, and source maps to aid debugging.

Runtime and interoperability: JavaScriptiin code runs on modern browsers and Node.js, with bridges to existing JavaScript libraries. Interop is achieved via wrappers that translate between JavaScript-valued types and JavaScriptiin types.

History and status: The language appears in community discussions and experimental repositories dating from the mid-2020s. It remains unofficial and speculative, with no formal standard or widespread adoption.
