- The parseInt() function parses a string and returns an integer.
- The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.
- Only the first number in the string is returned.
- If the first character cannot be converted to a number, parseInt() returns NaN.
Code:-
