how to get a random number from a range in javascript code example

Example 1: 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 2: javascript get random integer in given range

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

Example 3: random number in range js

var min = 10, max = 25;
//inclusive random (can output 25)
var random = Math.round(Math.random() * (max - min) + min);
//exclusive random (max number that can be output is 24, in this case)
var random = Math.floor(Math.random() * (max - min) + min);
//floor takes the number beneath the generated random and round takes
//which ever is the closest to the decimal
