javascript random number code example

Example 1: 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.

Example 2: 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 3: js random number

var random;
var max = 8
function findRandom() {
  random = Math.floor(Math.random() * max) //Finds number between 0 - max
  console.log(random)
}
findRandom()

Example 4: random number generator javascript

Math.floor(Math.random() * (max - min + 1)) + min;
//max is the highest number you want it to get
//min is the lowest number you want it to get

Example 5: javascript random number

Math.random() * 10 = 0-10

Example 6: javascript random number

const randomVCC = () => {
	const cc = 4728398706189983
	const randomVirtualCreditCard = Math.random(cc).toString().replace('0.', '')
	const visaCreditCard = 4 + randomVirtualCreditCard
	const pattern = /\d{16}/.exec(+visaCreditCard).join('')
    return typeof +pattern === 'number' && +pattern
}
console.log(randomVCC())
