Ranged random nums

// two ways to get a random integer between zero and another (e.g. between 0 and 100)

// method 1
// Math.trunc (new ES6) truncates the floating point, converting the value to an integer.
const maxVal = 100;
const randomInt = Math.trunc(maxVal * Math.random());


// method 2
// the left shift operator (<<) 
// Bitwise shifting any 
// number x to the left by y bits yields x * 2 ** y. 
// So e.g.: 9 << 3 translates to: 9 * (2 ** 3) = 9 * (8) = 72.
const maxVal = 100;
const randomInt = (maxVal * Math.random()) << 0;


// BONUS
//here is something from MDN for random numbers in a range
function getRandomIntInclusive(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1) + min); //The maximum is inclusive and the minimum is inclusive
}
