InteractionManager allows long-running work to be scheduled after any interactions/animations have completed. In particular, this allows JavaScript animations to run smoothly.

Applications can schedule tasks to run after interactions with the following:

InteractionManager.runAfterInteractions(() => {
  // ...long-running synchronous task...
});

Compare this to other scheduling alternatives:

• requestAnimationFrame(): for code that animates a view over time.
• setImmediate/setTimeout(): run code later, note this may delay animations.
• runAfterInteractions(): run code later, without delaying active animations.

The touch handling system considers one or more active touches to be an 'interaction' and will delay runAfterInteractions() callbacks until all touches have ended or been cancelled.
