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
}javascript random
function random(min, max) {
return ~~(Math.random() * (max - min + 1) + min);
}
random(1, 5);javascript get random number
// Returns an integer between min and max (the maximum is exclusive and the minimum is inclusive)
function getRandomInt(min, max) {
min = Math.ceil(min);
max = Math.floor(max);
return Math.floor(Math.random() * (max - min) + min);
}javascript randint
/* If 1 argument is given, minimum will be set to 0 and maximum to this argument
* If 2 arguments were given, the fist would be the minimum and the second the maximum
* The function will return an integer in [min, max[
*/
const Math.randint = function (min,max) {
[min,max] = (max===undefined)?[0,min]:(min>max)[max,min]:[min,max];
return Math.floor(Math.random*(max-min)+min);
}javascript random()
var randomNo = Math.floor(Math.rand() * 10000000001);
console.log(randomNo);
