What is apex:repeat is used for VisualForce pages in Salesforce?

Hi Deepak,
An iteration component that allows you to output the contents of a collection according to a structure that you specify. The collection can include up to 1,000 items.
for example,
<apex:page controller="repeatCon" id="thePage">
<apex:repeat value="{!strings}" var="string" id="theRepeat">
<apex:outputText value="{!string}" id="theValue"/>
</apex:repeat>
</apex:page>
/*** Controller: ***/
public class repeatCon {
public String[] getStrings() {
return new String[]{'ONE','TWO','THREE'};
}
}
