random integer function js

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 }

generate random integer javascript

/**
 * Returns a random number between min (inclusive) and max (exclusive)
 */
function getRandomArbitrary(min, max) {
    return Math.random() * (max - min) + min;
}

/**
 * Returns a random integer between min (inclusive) and max (inclusive).
 * The value is no lower than min (or the next integer greater than min
 * if min isn't an integer) and no greater than max (or the next integer
 * lower than max if max isn't an integer).
 * Using Math.round() will give you a non-uniform distribution!
 */
function getRandomInt(min, max) {
    min = Math.ceil(min);
    max = Math.floor(max);
    return Math.floor(Math.random() * (max - min + 1)) + min;
