special operators

Javascript supports a number of special operators that do not fit into the operators catagories.

1.       The delete operator

2.       The new operator

3.       The void operator

Delete operator:

The delete operator is used to  delete a property of an object or an element at an array index.

Example:

Delete myArray[5];//deletes the sixth element of myArray;

New Operator

It is used to  create an object .

Example:

A=new Array();

This will create a new JavaScript object of the type array and assign this array to a context area in memory called ‘A’

The void operator

The void operator does not return a value. It is typically used in JavaScript to return a URL with no value.
