js get random number between 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: math.random javascript

Math.random() 
// will return a number between 0 and 1, you can then time it up to get larger numbers.
//When using bigger numbers remember to use Math.floor if you want it to be a integer
Math.floor(Math.random() * 10) // Will return a integer between 0 and 9
Math.floor(Math.random() * 11) // Will return a integer between 0 and 10

// You can make functions aswell 
function randomNum(min, max) {
	return Math.floor(Math.random() * (max - min)) + min; // You can remove the Math.floor if you don't want it to be an integer
}

Example 3: 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 4: random in a range js

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

Example 5: Generate random whole numbers within a range javascript

function randomRange(min, max) {

	return Math.floor(Math.random() * (max - min + 1)) + min;

}

console.log(randomRange(1,9));

Example 6: Math.random javascript double

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