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
//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));
//if you want a random integer number from one number to another
//(including the min and the max numbers), you can use this function
function getRandomIntBetween(min, max) {
min = Math.ceil(min);
max = Math.floor(max);
return Math.floor(Math.random() * (max - min + 1)) + min;
}
//Returns a random integer number from 0 to 25
console.log(getRandomIntInclusive(0,25));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);
