typescript

This is a Rust native implementation of a Typescript Parser and a JIT execution engine.

This project comes in two crates:

  • [typescript-ast]: Parses Typescript into an AST.
  • [typescript-jit]: Takes an AST representation and creates an executable script.

State:

  • Parser: Async/Await are missing.
  • JIT: Creates functional binary code for functions.

Why?

  • Because V8 is to compllicated to "just integrate it".
  • rquickjs makes problems in an multi threaded environment.
  • And lua is fast, but ugly for larger scripts.

Features

  • Parses Typescript via Pest.
  • A LLVM based JIT execution engine.
