math random in js 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: generate random numbers in js

Math.floor((Math.random() * 100) + 1);
//Generate random numbers between 1 and 100
//Math.random generates [0,1)

Example 3: generate random number javascript

function randomNumber(min, max) {
  return Math.floor(Math.random() * (max - min)) + min;
}

Example 4: javascript random number between 0 and 10

Math.floor(Math.random() * 10);

Example 5: angular random number between 1 and 10

function randomNumber(min, max) {
  return Math.random() * (max - min) + min;
}

Example 6: javascript random

function random(min, max) {
  return ~~(Math.random() * (max - min + 1) + min);
}
random(1, 5);
