|
* 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
