Type Cast in Java Script

In js, variables are created as var type. That means, js engine can cast it to the original type by itself.

parseInt(12) will be converted 12 to an Integer value.

           Example                           Result 
parseInt("12")                          12
parseInt("12.657")                    12
parseInt("12aaaa")                   12
parseInt("aaaa")                NaN (means "Not a Number")
