 A major feature used by C/C++/C# implementation of SimConnect client libraries is the ability to directly cast a memory block to a user-defined structure. This is technically impossible to do in JavaScript or TypeScript since memory layout of classes and types are not accessible. Consequently, the wrapping/unwrapping steps must be done by the user.
