When reveal.js is booted up via `Reveal.initialize()`, it will go through all registered plugins and invoke their "init" methods. If the "init" method returns a Promise, reveal.js will wait for that promise to be fullfilled before finshing the startup sequence and firing the [ready](#ready-event) event. Here's an example of a plugin that returns a promise:

 |

```
 |

```javascript
 | 
			
		||||
Reveal.registerPlugin( 'myPlugin', {
 | 
			
		||||
	init: () => {
 | 
			
		||||
		return new Promise( resolve => setTimeout( resolve, 3000 ) );
 | 
			
		||||
	}
 | 
			
		||||
	init: () =>  new Promise( resolve => setTimeout( resolve, 3000 ) )
 | 
			
		||||
} );
 | 
			
		||||
Reveal.addEventListener( 'ready', () => console.log( 'Three seconds later...' ) );
