js math random range code example

Example 1: random int between two numbers javascript

// Between any two numbers
Math.floor(Math.random() * (max - min + 1)) + min;

// Between 0 and max
Math.floor(Math.random() * (max + 1));

// Between 1 and max
Math.floor(Math.random() * max) + 1;

Example 2: javascript get random number in range

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

//usage example: getRandomNumberBetween(20,400);

Example 3: random in a range js

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

Example 4: javascript get random integer in given range

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

Example 5: javascript random number between 0 and 10

Math.floor(Math.random() * 10);

Example 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
}
