## Descripción

Emite todos los valores del Observable fuente en un array cuando este se completa.

![Diagrama de canicas del operador toArray](https://github.com/puntotech/rxjs-docu/blob/master/doc/operators/utility/assets/images/marble-diagrams/utility/toArray.png)

toArray espera a que el Observable fuente se complete para emitir un array que contiene todas sus emisiones. Si el Observable fuente emite un error, no se emitirá ningún array.

## Ejemplos

**Emitir un array que contenga los números del 1 al 5**

StackBlitz

```javascript
import { toArray } from "rxjs/operators";
import { range } from "rxjs";

const number$ = range(1, 5);

number$.pipe(toArray()).subscribe(console.log);
// Salida: [ 1, 2, 3, 4, 5]
```

**Emitir un array que contenga las primeras 4 teclas pulsadas**

StackBlitz

```typescript
import { fromEvent } from "rxjs";
import { map, take, toArray } from "rxjs/operators";

const key$ = fromEvent<KeyboardEvent>(document, "keydown");

key$
  .pipe(
    take(4),
    map(({ code }) => code),
    toArray()
  )
  .subscribe(console.log);
// Salida: [ 'KeyR', 'KeyX', 'KeyJ', 'KeyS' ]
```

### Ejemplo de la documentación oficial

```javascript
import { interval } from "rxjs";
import { toArray, take } from "rxjs/operators";

const source = interval(1000);
const example = source.pipe(take(10), toArray());

const subscribe = example.subscribe((val) => console.log(val));

// Salida: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
```
