math.random()*i 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: js random

Math.floor(Math.random() * 10) + 1 // Random number Between 1 and 10
// First Math.random give us a random number between 0 and 0,99999
// The we multiply it by 10
// And we round dow with Math.floor
// We add 1 so the result will never be 0 

// Another Example:
h.floor(Math.random() * 20) + 10 // Random number Between 10 and 20
