javascript random number

Math.floor(Math.random() * 6) + 1  

function getRandomNumberBetween(min,max){
    return Math.floor(Math.random()*(max-min+1)+min);
}

//usage example: getRandomNumberBetween(20,400); 

var random;
var max = 8
function findRandom() {
  random = Math.floor(Math.random() * max) //Finds number between 0 - max
  console.log(random)
}
findRandom()

var RandomNumber = Math.ceil(Math.random() * 100);              
// Returns a random number between 1 and 100

Math.floor(Math.random() * 100);     // returns a 
  random integer from 0 to 99
