/**
|
|
* The Max operator operates on an Observable that emits numbers (or items that can be compared with a provided function),
|
|
* and when source Observable completes it emits a single item: the item with the largest value.
|
|
*
|
|
* 
|
|
*
|
|
* ## Examples
|
|
* Get the maximal value of a series of numbers
|
|
* ```ts
|
|
* import { of } from 'rxjs';
|
|
* import { max } from 'rxjs/operators';
|
|
*
|
|
* of(5, 4, 7, 2, 8).pipe(
|
|
* max(),
|
|
* )
|
|
* .subscribe(x => console.log(x)); // -> 8
|
|
* ```
|
|
*
|
|
* Use a comparer function to get the maximal item
|
|
* ```typescript
|
|
* import { of } from 'rxjs';
|
|
* import { max } from 'rxjs/operators';
|
|
*
|
|
* interface Person {
|
|
* age: number,
|
|
* name: string
|
|
* }
|
|
* of<Person>(
|
|
* {age: 7, name: 'Foo'},
|
|
* {age: 5, name: 'Bar'},
|
|
* {age: 9, name: 'Beer'},
|
|
* ).pipe(
|
|
* max<Person>((a: Person, b: Person) => a.age < b.age ? -1 : 1),
|
|
* )
|
|
* .subscribe((x: Person) => console.log(x.name)); // -> 'Beer'
|
|
* ```
|
|
*
|
|
* @see {@link min}
|
|
*
|
|
* @param {Function} [comparer] - Optional comparer function that it will use instead of its default to compare the
|
|
* value of two items.
|
|
* @return {Observable} An Observable that emits item with the largest value.
|
|
* @method max
|

* @owner Observable
