### `Rx.Observable.prototype.bufferWithCount(count, [skip])`
[Ⓢ](https://github.com/Reactive-Extensions/RxJS/blob/master/src/core/linq/observable/bufferwithcount.js)

Projects each element of an observable sequence into zero or more buffers which are produced based on element count information.

#### Arguments
1. `count` *(`Function`)*: Length of each buffer.
2. `[skip]` *(`Function`)*: Number of elements to skip between creation of consecutive buffers. If not provided, defaults to the count.

#### Returns
*(`Observable`)*: An observable sequence of buffers.

#### Example
```js
/* Without a skip */
var source = Rx.Observable.range(1, 6)
    .bufferWithCount(2);

var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x.toString());
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });

// => Next: 1,2
// => Next: 3,4
// => Next: 5,6
// => Completed

/* Using a skip */
var source = Rx.Observable.range(1, 6)
    .bufferWithCount(2, 1);

var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x.toString());
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });

// => Next: 1,2
// => Next: 2,3
// => Next: 3,4
// => Next: 4,5
// => Next: 5,6
// => Next: 6
// => Completed
```
