It's recommended to pull in the Observable creation methods you need directly from 'rxjs' as shown below with range.
If you're using RxJS version 7.2 or above, you can pull in any operator you need from the same spot, 'rxjs'.
import { range, filter, map } from 'rxjs';
range(1, 200)
.pipe(
filter(x => x % 2 === 1),
map(x => x + x)
)
.subscribe(x => console.log(x));
If you're using RxJS version below 7.2, you can pull in any operator you need from one spot, under 'rxjs/operators'.

.pipe(
filter(x => x % 2 === 1),
map(x => x + x)
)
.subscribe(x => console.log(x));
