* Async Scheduler
|

|

|

|
|
* <span class="informal">Schedule task as if you used setTimeout(task, duration)</span>
|
||
|
|
*
|
||
|
|
* `async` scheduler schedules tasks asynchronously, by putting them on the JavaScript
|
||
|
|
* event loop queue. It is best used to delay tasks in time or to schedule tasks repeating
|
||
|
|
* in intervals.
|
||
|
|
*
|
||
|
|
* If you just want to "defer" task, that is to perform it right after currently
|
||
|
|
* executing synchronous code ends (commonly achieved by `setTimeout(deferredTask, 0)`),
|
||
|
|
* better choice will be the {@link asap} scheduler.
|
||
|
|
*
|
||
|
|
* @example <caption>Use async scheduler to delay task</caption>
|
||
|
|
* const task = () => console.log('it works!');
|
||
|
|
*
|
||
|
|
* Rx.Scheduler.async.schedule(task, 2000);
|
||
|
|
*
|
||
|
|
* // After 2 seconds logs:
|
||
|
|
* // "it works!"
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* @example <caption>Use async scheduler to repeat task in intervals</caption>
|
||
|
|
* function task(state) {
|
||
|
|
* console.log(state);
|
||
|
|
* this.schedule(state + 1, 1000); // `this` references currently executing Action,
|
||
|
|
* // which we reschedule with new state and delay
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* Rx.Scheduler.async.schedule(task, 3000, 0);
|
||
|
|
*
|
||
|
|
* // Logs:
|
||
|
|
* // 0 after 3s
|
||
|
|
* // 1 after 4s
|
