# Enums

A naive JavaScript implementation of Enum and Mirror.

## Mask

```javascript

var Mask = require('enums').Mask;

```

```javascript

var Access = Mask([

	'USER',

	'ADMIN',

	'OWNER'

]);

// { USER: 1, ADMIN: 2, OWNER: 4 }

var canDelete = Access.ADMIN | Access.OWNER;

Boolean(Access.USER & canDelete); // false

Boolean(Access.ADMIN & canDelete); // true

```

```javascript

var NodeFilter = Mask([

	'ELEMENTS',

	'COMMENTS',

	'ATTRIBUTES',

	'TEXT'

], true);

// { ALL: 15, ELEMENTS: 1, COMMENTS: 2, ATTRIBUTES: 4, TEXT: 8 }

var whatToShow = NodeFilter.ALL;

Boolean(NodeFilter.COMMENTS & whatToShow); // true

```

## Mirror

```javascript

var Mirror = require('enums').Mirror;

```

```javascript

var Actions = Mirror([

	'TODO_ADDED',

	'TODO_REMOVED',

	'TODO_UPDATED'

]);

// { TODO_ADDED: 'TODO_ADDED',

//   TODO_REMOVED: 'TODO_REMOVED',

//   TODO_UPDATED: 'TODO_UPDATED' }

```
