Window: scheduler property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The scheduler read-only property of the Window interface is the entry point for using the Prioritized Task Scheduling API.

It returns a Scheduler object instance containing postTask() and yield() methods that can be used to schedule prioritized tasks.

Value

A Scheduler.

Examples

The code below shows a very basic use of the property and its associated interface. It demonstrates how to check that the property exists and then posts a task that returns a promise.

For comprehensive example code showing to use the API see Prioritized Task Scheduling API > Examples.
