Answer 1

It uses substring method to extract a string of 2 characters after every 2 index starting from index 0. Example,

if hex value is "ec45f3" then (0,2) will give us a string of "ec", (2,4) will give us a string of "45" and (4, 6) => "f3".

now it provides those substrings to parseInt method which tries to convert them into integer(which is what rgb presents) from hex values (indicated by base 16 passed as second argument to parseInt)
