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
}

Math.random() // Returns number from 0 to 1. 

Math.floor(Math.random() * max) // Return number from 0 to max minus 1
// Example
Math.floor(Math.random() * 10) // Return number from 0 to 9
// Add a +1 to return a number from 0 to max
Math.floor(Math.random() * 10) + 1 // Returns Number from 1 to 10
// To have a min and max 
Math.floor(Math.random() * (max - min)) + min
// Example
Math.floor(Math.random() * (20 - 10)) + 10
