/**
|
|
*
|
|
* Asap Scheduler
|
|
*
|
|
* <span class="informal">Perform task as fast as it can be performed asynchronously</span>
|
|
*
|
|
* `asap` scheduler behaves the same as {@link async} scheduler when you use it to delay task
|
|
* in time. If however you set delay to `0`, `asap` will wait for current synchronously executing
|
|
* code to end and then it will try to execute given task as fast as possible.
|
|
*
|
|
* `asap` scheduler will do its best to minimize time between end of currently executing code
|
|
* and start of scheduled task. This makes it best candidate for performing so called "deferring".
|
|
* Traditionally this was achieved by calling `setTimeout(deferredTask, 0)`, but that technique involves
|
|
* some (although minimal) unwanted delay.
|
|
*
|
|
* Note that using `asap` scheduler does not necessarily mean that your task will be first to process
|
|
* after currently executing code. In particular, if some task was also scheduled with `asap` before,
|
|
* that task will execute first. That being said, if you need to schedule task asynchronously, but
|
|
* as soon as possible, `asap` scheduler is your best bet.
|
|
*
|
|
* @example <caption>Compare async and asap scheduler</caption>
|
|
*
|
|
* Rx.Scheduler.async.schedule(() => console.log('async')); // scheduling 'async' first...
|
|
* Rx.Scheduler.asap.schedule(() => console.log('asap'));
|
|
*
|
|
* // Logs:
|
|
* // "asap"
|
|
* // "async"
|
|
* // ... but 'asap' goes first!
|
|
*
|
|
* @static true
|
|
* @name asap
|
|
* @owner Scheduler
