- * Animation Frame Scheduler
- *
- * <span class="informal">Perform task when `window.requestAnimationFrame` would fire</span>
- *
- * When `animationFrame` scheduler is used with delay, it will fall back to {@link asyncScheduler} scheduler
- * behaviour.
- *
- * Without delay, `animationFrame` scheduler can be used to create smooth browser animations.
- * It makes sure scheduled task will happen just before next browser content repaint,
- * thus performing animations as efficiently as possible.
- *
- * ## Example
- * Schedule div height animation
- * ```ts
- * // html: <div style="background: #0ff;"></div>
- * import { animationFrameScheduler } from 'rxjs';
- *
- * const div = document.querySelector('div');
- *
- * animationFrameScheduler.schedule(function(height) {
- * div.style.height = height + "px";
- *
- * this.schedule(height + 1); // `this` references currently executing Action,
- * // which we reschedule with new state
- * }, 0, 0);
- *
- * // You will see a div element growing in height
- * ```

- export const animationFrameScheduler = new AnimationFrameScheduler(AnimationFrameAction);
- /**
- * @deprecated Renamed to {@link animationFrameScheduler}. Will be removed in v8.
