Generate random whole numbers within a range javascript

function randomRange(min, max) {

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

}

console.log(randomRange(1,9));

random in range js

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

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 
}

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

random in a range js

const rnd = (min,max) => { return Math.floor(Math.random() * (max - min + 1) + min) };

random number in range js

var min = 10, max = 25;
//inclusive random (can output 25)
var random = Math.round(Math.random() * (max - min) + min);
//exclusive random (max number that can be output is 24, in this case)
var random = Math.floor(Math.random() * (max - min) + min);
//floor takes the number beneath the generated random and round takes
//which ever is the closest to the decimal

javascript get random integer in given range

const randomInteger = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min;

javascript random int in range

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

console.log(randomInt(1, 6)) // random integer between 1 and 6

javascript random number in range

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

js random in range

function ran(min, max, exclude = false) {
  let range = max - min + 1;

  //if you don't want to exclude any number then just returns numbr in range
  if (!exclude) return Math.floor(Math.random() * range + min);
  //If you want to exlude only one number then here's O(1) solution.
  //number from range 1-4 but never get 3:
  //get number between 1-3 and if its 3 then return 4
  if (!exclude?.length) {
    let num = Math.floor(Math.random() * (range - 1) + min);
    return num == exclude ? range : num;
  }
  //if you want to exlude multiple numbers here's O(n) solution:
  //foreach number in range i want to check if its not on exlude list
  //but i dont want to use indexOf or find functions as they are O(n) making this O(n^2)
  //i create object with keys being exluded numbers as reading object by key is O(1)
  // ?. operator returns null if such key doesnt have value
  let badNum = {};
  for (let i = 0; i < exclude.length; i++) {
    badNum[exclude[i]] = true;
  }
  let googNum = [];
  for (let i = 0; i < range; i++) {
    if (!badNum?.[i]) googNum.push(i);
  }
  return googNum[Math.floor(Math.random() * googNum.length)];
}

random number generator javascript with range

function randomNumberGeneratorInRange(rangeStart, rangeEnd) {
   return Math.floor(Math.random() * (rangeStart - rangeEnd + 1) + rangeEnd);
}

console.log(`My random number: ${randomNumberGeneratorInRange(10, 50)}`);

math.random every number no range

int jj = reader.nextInt();

Random number given a range js

const randomNumber = ({ min, max } = { min: 0, max: 1 }) => {
  if (min >= max) {
    throw Error(
      `minimum value (${min}) is larger than or equal to maximum value (${max})`
    );
  }

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

// Usage: random number between 10 and 100.
const n = randomNumber({ min: 10, max: 100 });
