### `Rx.Observable.prototype.take(count, [scheduler])`
[Ⓢ](https://github.com/Reactive-Extensions/RxJS/blob/master/src/core/linq/observable/take.js "View in source")
Returns a specified number of contiguous elements from the start of an observable sequence, using the specified scheduler for the edge case of `take(0)`.
#### Arguments
1. `count` *(`Number`)*: The number of elements to return.
2. `[scheduler]` *(`Scheduler`)*: Scheduler used to produce an onCompleted message in case `count` is set to 0.
#### Returns
*(`Observable`)*: An observable sequence that contains the elements before and including the specified index in the input sequence.
#### Example
```js
var source = Rx.Observable.range(0, 5)
.take(3);
var subscription = source.subscribe(
function (x) {
console.log('Next: ' + x);
},
function (err) {
console.log('Error: ' + err);
},
function () {
console.log('Completed');
});
// => Next: 0
// => Next: 1
// => Next: 2
// => Completed
```
