It takes two parameters, the string to be parsed and the radix to be used. The radix is an integer between 2 and 36 which represents the base of the number. If parseInt() encounters a character while parsing that does not conform to the specified radix, it will ignore the character and all succeeding characters.

This NaN value is not a valid number for any radix and cannot be used in any mathematical calculation....
