Apex:actionsupport
Hi
I am trying to understand the actionsupport tag used in visualforce page. The classic defination is that it is a component that add support to another component that refreshed asynchonously when a particular event occurs.
Is it safe to assume that it is responsible to trigger controller actions in response to DOM element events.
why would i not use apex:commandButton instead? what is different?

A component that adds AJAX support to another component, allowing the component to be refreshed asynchronously by the server when a particular event occurs, such as a button click or mouseover

https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_charting_refreshing_data_actionsupport.htm
NOTE:- It allows components to be refreshed asynchronously by calling the controller’s method when any event occurs (like click on button). It allows us to do partial page refresh asynchronously without refreshing full page.
But in apex:commandButton full page will refreshed.
