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.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
}js random
function getRandomNumberBetween(min,max){
return Math.floor(Math.random()*(max-min+1)+min);
}
//usage example: getRandomNumberBetween(20,400);random js
function randomNumber(min, max) {
return Math.floor(Math.random() * (max - min)) + min + 1;
}javascript random number
//returns a random number between 1 and maxNumber
//replace Math.ceil with Math.round if you want to include 0 as well
const randomNumber = (maxNumber) => {
return Math.ceil(Math.random() * maxNumber);
}js math random
var n = Math.random();
n = Math.floor((n * 6) + 1); // if you want your numbers to start at 1 and end at 6
console.log(n);Copyright © 2021 Codeinu
