node.js random code example

Example 1: generate random number nodejs

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

Example 2: javascript randint

/* If 1 argument is given, minimum will be set to 0 and maximum to this argument
 * If 2 arguments were given, the fist would be the minimum and the second the maximum
 * The function will return an integer in [min, max[
 */
const Math.randint = function (min,max) {
  [min,max] = (max===undefined)?[0,min]:(min>max)[max,min]:[min,max];
  return Math.floor(Math.random*(max-min)+min);
}

Example 3: javascript pseudo random

var seed = 0;
var modulus = 2 ** 32;
var a = 1664525;
var c = 1013904223;

function getRandom() {
  var returnVal = seed / modulus;
  seed = (a * seed + c) % modulus;
  return returnVal;
}
