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);
Math.random() javascript
//Returns a number between 1 and 0
console.log(Math.random());
//if you want a random number between two particular numbers,
//you can use this function
function getRandomBetween(min, max) {
return Math.random() * (max - min) + min;
}
//Returns a random number between 20 and 170
console.log(getRandomBetween(20,170));
