Pull Request Overview

This PR implements a comprehensive "DIF execution" feature that adds a new DATEX Intermediate Format (DIF) execution layer to the DATEX JavaScript runtime. The changes introduce a new execution model with improved type handling, pointer management, and value serialization between JavaScript and the DATEX core runtime.

Key changes include:

  • Implementation of DIF (DATEX Intermediate Format) execution system with sync/async variants
  • Introduction of pointer management and reference handling with mutability controls
  • Addition of comprehensive test suites covering value parity, type conversion, and runtime execution

This comparison will never be true since value is declared as unknown but compared as a string literal. Should compare with typeof value === 'undefined' instead.

Suggested change
: value == "undefined"
: typeof value === "undefined"

The toArray() method doesn't exist on Map iterators. Should use Array.from(value.entries()).map(...) instead.

Suggested change
const map: [DIFValue, DIFValue][] = value.entries().map((
[k, v],
) => [
this.convertJSValueToDIFValue(k),
this.convertJSValueToDIFValue(v),
] as [DIFValue, DIFValue]).toArray();
const map: [DIFValue, DIFValue][] = Array.from(value.entries()).map(
([k, v]) => [
this.convertJSValueToDIFValue(k),
this.convertJSValueToDIFValue(v),
] as [DIFValue, DIFValue]
);
