Question:Briefly describe the new, delete and void operators? 

Answer New operator:All objects must begin with a constructor preceded by the new operator.
Example:
var family=new Array("Dad","Mom","Sue","Kris");
Delete operator:The delete operator removes an object property or an array element in a script.
Example:
var family=new Array("Dad","Mom","Sue","Kris");
delete family[2];
Void Operator:Void operator is unary and operates on any literal or variable.Usually, we will see this operator as part of an <A> tag in an HTML script.

<a href="javascript:void(0)" onClick="scroll(500,0)">
