## README

# object-identity-map

A subclass of `Map` based on object identity.
This allows objects that _look_ the same, but are
not the same reference, to map to the same value.

## Install

```sh
npm install object-identity-map
```

## Usage

```js
const ObjectIdentityMap = require('object-identity-map')

const map = new ObjectIdentityMap()

map.set({ foo: 'bar' }, true)

if (map.has({ foo: 'bar' })) {
  console.log(map.get({ foo: 'bar' }) === true)
}
```
