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

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.
*/
function getRandomInt(max) {
return Math.floor(Math.random() * Math.floor(max));
}

console.log(getRandomInt(3));
// expected output: 0, 1 or 2

console.log(getRandomInt(1));
// expected output: 0

console.log(Math.random());
// expected output: a number from 0 to <1``````
