### `Rx.Observable.prototype.max([comparer])`
[Ⓢ](https://github.com/Reactive-Extensions/RxJS/blob/master/src/core/linq/observable/max.js "View in source")
 
Returns the maximum value in an observable sequence according to the specified comparer.
 
#### Arguments
1. `[comparer]` *(`Function`)*:  Comparer used to compare elements.
 
#### Returns
*(`Observable`)*: An observable sequence containing a single element with the maximum element in the source sequence.
 
#### Example
```js
/* Without comparer */
var source = Rx.Observable.from([1,3,5,7,9,2,4,6,8])
    .max();
 
var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x);
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });
 
// => Next: 9
// => Completed
 
/* With a comparer */
function comparer (x, y) {
    if (x > y) {
        return 1;
    } else if (x < y) {
        return -1;
    }
    return 0;
}
 
var source = Rx.Observable.from([1,3,5,7,9,2,4,6,8])
    .max(comparer);
 
var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x);
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });
 
// => Next: 9
// => Completed
```
