What does parseInt() doing here?

Question

Image.style.left = parseInt(Image.style.left) + 10 + 'px';

Answer 1

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.
