A somewhat painful triple-nested ternary operator

Question

I went looking through Raphael.js\'s source code to find out how he converted RGB values to HSB. I found out the function he did it in and I was in the process

Answer 1

To my personal taste, a carefully aligned nested ternary beats the if-esle mess:

const H =
  C == 0 ? null            :
  V == r ? (g - b) / C     :
  V == g ? (b - r) / C + 2 :
           (r - g) / C + 4 ;
