What's the different between these two?

rgbColor = 'rgb(' + randomRGB() + ',' + randomRGB() + ',' + randomRGB() + ')';


rgbColor = rgb(randomRGB(), randomRGB() , randomRGB());

The first line sets the value of rgbColor to a string. The second is not a string. Assuming this is going to be used as a style in css, it a) needs to be a string because thats what css is read as. b) the second line just won't work as, if I'm not mistaken, rgb() is not a valid javascript function.
