Prioritized Task Scheduling API / 优先任务调度 API
The Prioritized Task Scheduling API provides a standardized way to prioritize all tasks belonging to an application, whether they defined in a website developer's code, or in third party libraries and frameworks.
Prioritized Task Scheduling API 提供了一种标准化方法来确定属于应用程序的所有任务的优先级，无论它们是在网站开发人员的代码中定义的，还是在第三方库和框架中定义的。
