• Asynchronous Background Processors - Offloads time-consuming native tasks to background threads to maintain responsiveness on the main JavaScript thread.
• Cross-Version Compatibility Gating - Hides V8 API differences behind macros and inline functions to ensure cross-version compatibility.
• V8 API Abstraction Layers - Acts as a compatibility layer allowing C++ code to compile against multiple versions of the V8 engine.
• Runtime API Wrappers - Hides V8 API version differences behind a single set of macros and inline functions for cross-version compatibility.
• Garbage Collection Prevention - Wraps function handles to ensure they are not garbage collected while background work is still in progress.
• Persistent Handle Management - Holds V8 object references that outlive handle scope disposal until they are explicitly freed.
• Native Type Converters - Translates V8 engine value types into native C++ types with success/failure signaling.
• Native Module Definitions - Defines the initialization function and exports the methods accessible to the JavaScript environment.
• Typed Arrays - Provides helper classes to access the raw binary contents of JavaScript typed arrays from native code.
• Native Property Accessors - Defines object properties with custom getters and setters to link native C++ data to JavaScript accessors.
• Persistent Object References - Provides a persistent reference manager to ensure V8 objects survive handle scope disposal until explicitly freed.
• String Encoding Converters - Converts between JavaScript string and byte encodings consistently across different V8 versions.
• Value Construction Helpers - Constructs JavaScript primitives and objects using a unified helper to maintain cross-version compatibility.
• Native-to-Script Function Invocations - Calls JavaScript functions from native code with support for context awareness and custom argument handling.
• Object Lifetime Management - Controls the lifetime of JavaScript objects by binding them to references to prevent premature garbage collection.
• Temporary Scope Management - Creates and disposes V8 handle scopes to safely manage object references across multiple Node versions.
• Runtime Exception Handling - Creates and throws typed JavaScript exceptions using helpers that abstract engine version differences.
• Cross-Environment Value Generators - Produces common JavaScript types like objects and booleans using a version-agnostic interface.

• Asynchronous Task Managers - Coordinates concurrent background operations and signals progress from native threads back to the main event loop.
• Native-to-JS Thread Dispatching - Provides a helper to run C++ work on background threads and invoke JavaScript callbacks upon completion.
• Value Type Conversions - Translates V8 engine value types into native C++ types with return signals for success tracking.
• Monadic Error Handling - Wraps engine handles in monadic Maybe types to ensure safe accessor methods and propagate emptiness.
• Monadic Containers - Encapsulates potentially empty V8 handles using monadic containers to avoid explicit null checks.
• Throw-Based Error Handlers - Processes typed errors by abstracting the creation and throwing mechanisms of the underlying JavaScript engine.
• Reference Lifecycle Management - Manages the lifecycle of persistent V8 object references that must survive handle scope disposal.
