-## Errors
-
-NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
-
-Note that an Error object is simply a specialized form of `v8::Value`.
-
-Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information.
