toArray will wait until the source Observable completes before emitting the array containing all emissions. When the source Observable errors no array will be emitted.

Example

import { interval } from 'rxjs';
import { toArray, take } from 'rxjs/operators';

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