 `Napi::Error` class extends `std::exception` and enables integrated
 error-handling for C++ exceptions and JavaScript exceptions.
 
+Note, that due to limitations of the N-API, if one attempt to cast the error object thrown as a primitive, an
+wrapped object will be received instead. (With properties ```isWrapObject``` and ```errorVal``` containing the primitive value thrown)

 The following sections explain the approach for each case:
