// The V8 implementation of N-API, including `js_native_api_v8.h` uses certain
// idioms which require definition here. For example, it uses a variant of
// persistent references which need not be reset in the constructor. It is the
// responsibility of this file to define these idioms. Optionally, this file
// may also define `NAPI_VERSION` and set it to the version of N-API to be
// exposed.

// In the case of the Node.js implementation of N-API some of the idioms are
// imported directly from Node.js by including `node_internals.h` below. Others
// are bridged to remove references to the `node` namespace. `node_version.h`,
// included below, defines `NAPI_VERSION`.
