What is the new way to define a variable in JavaScript?

Answer»

In the unsigned right SHIFT operator (>>>), the bits shifted on the left are always zero.

The zeros get filled in from the left with the operator. It shifts all bits in a 32-bit number to the right.

The following is an example:

&LT;html>    <BODY>       <script>          var val1 = -23;          var val2 = 2;          document.write("val1 >>> val2 = ");          res = (val1 >>> val2);          document.write(res);       </script>    </body> </html>

The OUTPUT:

val1 >>> val2 = 1073741818

Let us see another example wherein we have a positive number. In this CASE the operator works the same as a signed right shift:

<html>    <body>       <script>          var val1 = 7;          var val2 = 2;          document.write("val1 >>> val2 = ");          res = (val1 >>> val2);          document.write(res);       </script>    </body> </html>

The output:

val1 >>> val2 = 1
