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

| * ## Example |
| * A simple example emitting true if all elements are less than 5, false otherwise |
| * ```ts |
| * import { of } from 'rxjs'; |
| * import { every } from 'rxjs/operators'; |
| * |
| * of(1, 2, 3, 4, 5, 6).pipe( |
| * every(x => x < 5), |
| * ) |
| * .subscribe(x => console.log(x)); // -> false |
| * ``` |
| * |
| * @param {function} predicate A function for determining if an item meets a specified condition. |
| * @param {any} [thisArg] Optional object to use for `this` in the callback. |
| * @return {Observable} An Observable of booleans that determines if all items of the source Observable meet the condition specified. |
| * @method every |
