Explain Math.floor(Math.random())

Question

I have seen many places using Math.floor() and Math.random()

like below

$(\'a.random-color\').hover(function() { //mouseove         


        

Answer 1

Math.random returns value between 0 and 1. You are multiplying it with 256 so it will return some float value between 0 and 256. math.floor will omit fraction value from it.
