generate random int js code example

Example 1: generate random numbers in js

Math.floor((Math.random() * 100) + 1);
//Generate random numbers between 1 and 100
//Math.random generates [0,1)

Example 2: javascript random

function random(min, max) {
  return ~~(Math.random() * (max - min + 1) + min);
}
random(1, 5);

Example 3: 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 4: generate random int js

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