## gc-listen

A way to attach a JavaScript function with `napi_add_finalizer`. For debugging.

```javascript

const gcListen = require('gc-listen');

const obj = {};

const callback = () => {

    // …

};

gcListen(obj, callback);

```

`callback` won’t be called as long as `obj` isn’t eligible for garbage collection. N-API even suggests it will be called *when* `obj` is collected. It will always be called asynchronously when called at all.
