Could you build this?
No Creating a compiler and runtime that compiles JavaScript/TypeScript to native machine code with memory safety guarantees requires deep programming language theory, compiler engineering, and systems programming expertise.
What it would actually take: Building this requires designing a custom compiler frontend (parsing TS/JS AST) and backend (targeting LLVM or Cranelift) along with a custom garbage-free or reference-counted runtime in Rust. It requires building custom memory management semantics, static type analysis, async runtime executors (like Tokio bindings), and standard library implementations. Deep systems programming and compiler design expertise are essential.

Concerns raised: Number type ambiguity (ints vs floats vs longs in TypeScript), Search term collision with word 'script', Project name not distinctive enough
