### `Rx.Observable.range(start, count, [scheduler])`
[Ⓢ](https://github.com/Reactive-Extensions/RxJS/blob/master/src/core/linq/observable/range.js "View in source")
Generates an observable sequence of integral numbers within a specified range, using the specified scheduler to send out observer messages.
### Arguments
1. `start` *(`Number`)*: The value of the first integer in the sequence.
2. `count` *(`Number`)*: The number of sequential integers to generate.
3. `[scheduler=Rx.Scheduler.currentThread]` *(`Scheduler`)*: Scheduler to run the generator loop on. If not specified, defaults to Scheduler.currentThread.
#### Returns
*(`Observable`)*: An observable sequence that contains a range of sequential integral numbers.
#### Example
```js
var source = Rx.Observable.range(0, 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
```
