bts

bts stands for better ts: a Rust compiler for a strongly typed, C-like language that transpiles to JavaScript.

The language targets the JavaScript runtime directly, but it must be able to ingest TypeScript .d.ts files so programs can type-check against existing JavaScript and TypeScript ecosystems.

Core direction:

• C-like syntax without semicolons
• Strong static typing
• JavaScript output, not TypeScript output
• TypeScript declaration ingestion for interop
• Conventional compiler pipeline: lexing, parsing, lowering, type checking, analysis, and code generation

This repository is currently the compiler seed project.

• docs/comptime.md: user-facing comptime function guide
• docs/comptime-internals.md: compiler internals for comptime evaluation
