random number function javascript code example

Example 1: how to generate a random number in javascript

//To genereate a number between 0-1
Math.random();
//To generate a number that is a whole number rounded down
Math.floor(Math.random())
/*To generate a number that is a whole number rounded down between
1 and 10 */
Math.floor(Math.random() * 10) + 1 //the + 1 makes it so its not 0.

Example 2: generate random number javascript

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

Example 3: randint js

/* 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 => (min,max) {
  [min,max] = (max===undefined)?[0,min]:(min>max)[max,min]:[min,max];
  return Math.floor(Math.random*(max-min)+min);
}

Example 4: random number javascript

Math.floor(Math.random() * 11);      // returns a random integer from 0 to 10
Math.floor(Math.random() * 10) + 1;  // returns a random integer from 1 to 10

Example 5: random function javascript

let object = random(0, 50);
// making "object" a random number between 0 and 50.

console.log(object);
// printing object in the console

Example 6: random number in javascript

var randomNo = Math.floor(Math.rand() * 10000000001);
console.log(randomNo);

//This will generate random number
