# skip

#### signature: `skip(the: Number): Observable`

## Skip the provided number of emitted values.

### Why use `skip`?

Skip allows you to ignore the first x emissions from the source. Generally `skip` is used when you have an observable that always emits certain values on subscription that you wish to ignore. Perhaps those first few aren't needed or you are subscribing to a `Replay` or `BehaviorSubject` and do not need to act on the initial values. Reach for `skip` if you are only concerned about later emissions.

You could mimic `skip` by using [`filter`](https://www.learnrxjs.io/learn-rxjs/operators/filtering/filter) with indexes. Ex. `.filter((val, index) => index > 1)`

### Examples

**Example 1: Skipping values before emission**

( [StackBlitz](https://stackblitz.com/edit/typescript-o5ydjf?file=index.ts\&devtoolsheight=100))

```js
// RxJS v6+
import { interval } from 'rxjs';
import { skip } from 'rxjs/operators';

//emit every 1s
const source = interval(1000);
//skip the first 5 emitted values
const example = source.pipe(skip(5));
//output: 5...6...7...8........
const subscribe = example.subscribe(val => console.log(val));
```

#### Example 2: Short hand for a specific filter use case

( [StackBlitz](https://stackblitz.com/edit/typescript-yl3ap1?file=index.ts\&devtoolsheight=100) | [jsBin](http://jsbin.com/judamurego/edit?js,console) | [jsFiddle](https://jsfiddle.net/ElHuy/4jswLn3z/) )

```js
// RxJS v6+
import { from } from 'rxjs';
import { skip, filter } from 'rxjs/operators';

const numArrayObs = from([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);

// 3,4,5...
const skipObs = numArrayObs.pipe(skip(2)).subscribe(console.log);

// 3,4,5...
const filterObs = numArrayObs
  .pipe(filter((val, index) => index > 1))
  .subscribe(console.log);

//Same output!
```
