Rx.Observable.prototype.skipLast(count)

Ⓢ

Bypasses a specified number of elements at the end of an observable sequence.

This operator accumulates a queue with a length enough to store the first count elements. As more elements are received, elements are taken from the front of the queue and produced on the result sequence. This causes elements to be delayed.

Arguments

1. count (Number): Number of elements to bypass at the end of the source sequence.

Returns

(Observable): An observable sequence containing the source sequence elements except for the bypassed ones at the end.

Example

var source = Rx.Observable.range(0, 5)
    .skipLast(3);

var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x);
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });

// => Next: 0
// => Next: 1
// => Completed
