Renderer In Lightning Component Bundle

We use custom renderer to change or override the default rendering behavior of the component.

It automatically called when data is updated in the component.

There are four basic methods to render In the component.

1). render()
2). rerender()
3). afterRender()
4). unrender()

unrender():-
It call by framework when components is has been deleted.
Syntex:-
render : function(component, helper) {
var returnVal = this.superRender();
// Write your custom code here.
return returnVal;
}

rerender : function(component, helper) {
this.superRerender();
// Write your custom code here.
}

afterRender : function(component, helper) {
this.superAfterRender();
// Write your custom code here.
}

unRender : function(component, helper) {
this.superUnrender();
// Write your custom code here.
}
