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

Al contrario que [from](https://github.com/puntotech/rxjs-docu/blob/master/operators/creation/from/README.md), no se lleva a cabo ninguna aplanación y cada argumento al completo se emite como una notificación `next`.

// Salida: Angular, React, Vue
```
