how to write a program that shows a random number between 1 and 100 in your browser code example

Example 1: generate random number javascript

function randomNumber(min, max) {
  return Math.floor(Math.random() * (max - min)) + 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: how to write a program that shows a random number between 1 and 100 in your browser

var randomNum ;
randomNum = Math.ceil(Math.random() * 100);
document.write("Random number between 1 and 100: " + randomNum)
