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.
Comment

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
}

random number javascript

/* 
   The Math.random() function returns a floating-point, pseudo-random
   number in the range 0 to less than 1 (inclusive of 0, but not 1)
   with approximately uniform distribution over that range — which you
   can then scale to your desired range. The implementation selects the
   initial seed to the random number generation algorithm; it cannot
   be chosen or reset by the user.
*/

// expected output: 0, 1 or 2
