Value Render

This event is fired when when an app or component is rendered or rerendered. Handle this event using the aura:handler tag.

In this example, the onRender action in your client-side controller handles initial rendering and rerendering of the component. You can choose any name for the action attribute.

Setting value="{!this}" marks this as a value event. You should always use this setting for an init event.

The render event is fired after the init event, which is fired after component construction but before rendering.

For more information, see Handle the Render Event in the Lightning Aura Components Developer Guide.
