# es6-iterator
## ECMAScript 6 Iterator interface

### Installation

## API

### Constructors

#### Iterator(list) _(es6-iterator)_

Abstract Iterator interface. Meant for extensions and not to be used on its own.

Accepts any _list_ object (technically object with numeric _length_ property).

_Mind it doesn't iterate strings properly, for that use dedicated [StringIterator](#string-iterator)_

```javascript
var Iterator = require('es6-iterator')
var iterator = new Iterator([1, 2, 3]);

iterator.next(); // { value: 1, done: false }
iterator.next(); // { value: 2, done: false }
iterator.next(); // { value: 3, done: false }
iterator.next(); // { value: undefined, done: true }
```


#### ArrayIterator(arrayLike[, kind]) _(es6-iterator/array)_

Dedicated for arrays and array-likes. Supports three iteration kinds:
* __value__ _(default)_ - Iterates values
* __key__ - Iterates indexes
* __key+value__ - Iterates keys and indexes, each iteration value is in _[key, value]_ form.


```javascript
var ArrayIterator = require('es6-iterator/array')
var iterator = new ArrayIterator([1, 2, 3], 'key+value');

iterator.next(); // { value: [0, 1], done: false }
iterator.next(); // { value: [1, 2], done: false }
iterator.next(); // { value: [2, 3], done: false }
iterator.next(); // { value: undefined, done: true }
```

May also be used for _arguments_ objects:

```javascript
(function () {
  var iterator = new ArrayIterator(arguments);

  iterator.next(); // { value: 1, done: false }
  iterator.next(); // { value: 2, done: false }
  iterator.next(); // { value: 3, done: false }
  iterator.next(); // { value: undefined, done: true }
