Return with javascript

1

Hello,

I wish to make a variable which is a function that returns a random number when run.

for simple simon’s sake, here is a silly example …


var ran = function(){
   Math.random()*1;
   return;
}

console.log(ran); // gives me my random number
AND
console.log(ran+" "+ran); // gives me two different random numbers

Can someone help my syntax!?
Thanks
