Example
/* With no arguments */
var source = Rx.Observable.range(0, 3)
.do(function (x) { console.log('Do Next: ' + x); });
var subscription = source.subscribe();
// => Do Next: 0
// => Do Next: 1
// => Do Next: 2
/* With an observer */
var observer = Rx.Observer.create(
function (x) {
console.log('Next: %s', x);
},
function (err) {
console.log('Error: %s', err);
},
function () {
console.log('Completed');
});
var source = Rx.Observable.range(0, 3)
var subscription = source.subscribe(observer);
// => Next: 0
// => Next: 1
// => Next: 2
/* Using functions */
var source = Rx.Observable.range(0, 3)
var subscription = source.subscribe(
function (x) {
console.log('Next: %s', x);
},
