js random range number code example

Example 1: javascript random number in range

function getRandomIntInclusive(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1)) + min; //The maximum is inclusive and the minimum is inclusive 
}

Example 2: javascript generate a random integer number in a range of numbers

const min = 1;
const max = 4;
const intNumber = Math.floor(Math.random() * (max - min)) + min;
console.log(intNumber); //> 1, 2, 3

Example 3: 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 4: 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) )
}
