  4. * Returns an Observable that emits whether or not every item of the source satisfies the condition specified.

  7. * A simple example emitting true if all elements are less than 5, false otherwise

  11. *
  12. * of(1, 2, 3, 4, 5, 6).pipe(
  13. * every(x => x < 5),
  14. * )
  15. * .subscribe(x => console.log(x)); // -> false
  16. * ```
  17. *
  18. * @param {function} predicate A function for determining if an item meets a specified condition.
  19. * @param {any} [thisArg] Optional object to use for `this` in the callback.
  20. * @return {Observable} An Observable of booleans that determines if all items of the source Observable meet the condition specified.
