`Rx.Observable.prototype.bufferWithTimeOrCount(timeSpan, count, [scheduler])`

Ⓢ

Projects each element of an observable sequence into a buffer that is completed when either it's full or a given amount of time has elapsed.

Arguments

timeSpan (Number): Maximum time length of a buffer.

Example

/* Hitting the count buffer first */
var source = Rx.Observable.interval(100)
    .bufferWithTimeOrCount(500, 3)
    .take(3);

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