Generate random whole numbers within a range javascript

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

//usage example: getRandomNumberBetween(20,400); 
const min = 1;
const max = 4;
const intNumber = Math.floor(Math.random() * (max - min)) + min;
console.log(intNumber); //> 1, 2, 3var myMin = 1;
var myMax = 10;
function randomRange(myMin, myMax) {
  return Math.floor(Math.random() * (myMax - myMin + 1)) + myMin;
}

console.log(randomRange(myMin, myMax));function randomRange(min, max) {

	return Math.floor(Math.random() * (max - min + 1)) + min;

}

console.log(randomRange(1,9));var randomWholeNumber = Math.floor(Math.random() * 20);


function randomWholeNum() {

	return Math.floor(Math.random() * 10);

}

console.log(randomWholeNum());
