# 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.

## typescript-jit usage
