# This is RxJS v 4. [Find the latest version here](https://github.com/reactivex/rxjs)### `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. #### Arguments1. `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```### Location File:- [`/src/core/linq/observable/bufferwithcount.js`](https://github.com/Reactive-Extensions/RxJS/blob/master/src/core/linq/observable/bufferwithcount.js) Dist:- [`rx.js`](https://github.com/Reactive-Extensions/RxJS/blob/master/dist/rx.js)- [`rx.compat.js`](https://github.com/Reactive-Extensions/RxJS/blob/master/dist/rx.compat.js)- [`rx.all.js`](https://github.com/Reactive-Extensions/RxJS/blob/master/dist/rx.all.js)- [`rx.all.compat.js`](https://github.com/Reactive-Extensions/RxJS/blob/master/dist/rx.all.compat.js)- [`rx.lite.extras.js`](https://github.com/Reactive-Extensions/RxJS/blob/master/dist/rx.lite.extras.js) Prerequisites:- None NPM Packages:- [`rx`](https://www.npmjs.org/package/rx) NuGet Packages:- [`RxJS-All`](http://www.nuget.org/packages/RxJS-All/)- [`RxJS-Main`](http://www.nuget.org/packages/RxJS-Main/)- [`RxJS-Lite`](http://www.nuget.org/packages/RxJS-Lite/) Unit Tests:- [`/tests/observable/bufferwithcount.js`](https://github.com/Reactive-Extensions/RxJS/blob/master/tests/observable/bufferwithcount.js)
