var source = Rx.Observable.for(
    array,
    function (x) {
        return Rx.Observable.timer(x)
    })
    .map(function(x, i) { return i; })
    .debounceWithSelector(function (x) {
        return Rx.Observable.timer(700);
    });

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