random method in javascript code example
Example 1: 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
}
Example 2: random int javascript
//Returns random Int between 0 and 2 (included)
Math.floor(Math.random()*3)
Example 3: 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);
}
Example 4: random number javascript
Math.floor(Math.random() * 11); // returns a random integer from 0 to 10
Math.floor(Math.random() * 10) + 1; // returns a random integer from 1 to 10
