Question
i'm trying to determine if a color has been supplied as an optional argument to a function. in order to determine this, i'm simply writing if(color){...} and supplying NaN if i don't want there to be a color.
however, it seems that the color black (0x000000) also equates to NaN. how can i determine if a supplied color number argument is present and black if 0x000000 is passed as the argument?
Solution
Some source code would be appropriate.
It sounds like you are saying that the following are equivalent:
if ( NaN ) {}
if ( 0x000000 ) {}
which is true. I think you want:
if ( isFinite( color ) ) {}
