Answer 2

you cannot make an animation with a simple loop... you need to cyclicly update display in a kind of loop, by regularly but async call function(s) to do the (frame) update (using setInterval, setTimeout or requestAnimationFrame)

Math.random is a function wich return a number between [0; 1[

so it's used to generate random values wich could be used inside animation ^^
