/**
* Converts the arguments to an observable sequence.
*
* <span class="informal">Each argument becomes a `next` notification.</span>
*
* 
*
* Unlike {@link from}, it does not do any flattening and emits each argument in whole
* as a separate `next` notification.
*
* ## Examples
*
* Emit the values `10, 20, 30`
*
* ```ts
* import { of } from 'rxjs';
*
* of(10, 20, 30)
* .subscribe({
* next: value => console.log('next:', value),
* error: err => console.log('error:', err),
* complete: () => console.log('the end'),
* });
*
* // Outputs
* // next: 10
* // next: 20
* // next: 30
* // the end
* ```
*
* Emit the array `[1, 2, 3]`
*
* ```ts
* import { of } from 'rxjs';
*
* of([1, 2, 3])
* .subscribe({
* next: value => console.log('next:', value),
* error: err => console.log('error:', err),
* complete: () => console.log('the end'),
* });
*
* // Outputs
* // next: [1, 2, 3]
* // the end
* ```
*
* @see {@link from}
* @see {@link range}
*
* @param {...T} values A comma separated list of arguments you want to be emitted
* @return {Observable} An Observable that emits the arguments
* described above and then completes.
