Subject: [Javascript] How do I convert "FF" to 255?

Hello.

How can I get an highlighted version of a color.
That is, how can I find the code of a color wich is a lighter version of
another color.
I tryed to do this myself but I need, for instance, to know how to get a
number from a string representing an hexadecimal number.
I could then add some value to RGB components and use RGB(newred, newgreen,
newblue) to get that color.
I found Hex function that returns a string representing the hexadecimal
convertion of a number.
Is there an inverse function to turn a string into a number?
Something like afunc("FF") that returns 255.

Thanks
