What is the purpose of the ion-refresher component in Ionic?
Refreshing means updating of the currently displayed page so that the user can see the latest content. Ionic provides the <ion-refresher> component to add pull-to-refresh functionality on a content component. An Ionic allows the users to pull the page down from the top on a list of data using touch to retrieve more data. The updated data should be modified during the refresher's output events. Once, the refreshing of page ends, call the complete() function on the refresher.
