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

Example 5: angular random number between 1 and 10

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

Example 6: javascript random

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