⚠️ Limitations

TypeScript Native

  • No eval or dynamic object modification
    Code is strictly compiled; object structures must be static and known at compile time.
  • Strict mode only (strict)
    Enforced type safety — usage of any and unknown is disallowed.
  • Tuple and array constraints
    Only homogeneous arrays and statically indexed tuples are supported.
  • Partial JS feature support
    Features like Function.bind with generics or for..of over tuples are not supported.

C++ Integration

  • No exception passing between C++ and TypeScript
  • TypeScript objects are not thread-safe
    Do not pass them into other threads.
  • Pointer-based API and inheritance from Object required
    All exported arguments and return types must be pointers to classes with Object as the first base class.
  • Function overloading is not supported for exports
  • Stack objects cannot be captured or passed to TS
