hOW TO make the Math.random return a value between 0 and 1 code example

Example 1: javascript get random number in range

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

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

Example 2: javascript get random array of integre in given range

const randomArrayInRange = (min, max, n) => Array.from({ length: n }, () => Math.floor(Math.random() * (max - min + 1)) + min);

// Example
randomArrayInRange(1, 100, 10);

Example 3: function to get random number from min max range

funtion getRandomNumber(min, max) {
min = Math.ceil(min);
max = Math.floor(max);
return Math.floor(Math.random() * (max-min) )
}
