Scheduler Polyfill

This is a polyfill for the Prioritized Task Scheduling API. Documentation on the API shape along with examples can be found in the explainer.

The polyfill includes implementations of Scheduler, exposed through self.scheduler, as well as TaskController and TaskPriorityChangeEvent classes.

The implementation uses a combination of setTimeout, MessageChannel, and requestIdleCallback to implement task scheduling, falling back to setTimeout when other APIs are not available.

Requirements

A browser that supports ES6 is required for this polyfill.
