Random-number-generation function, useful for luck-based code

rng.js

function findChoice() {
  // local var generating random number, then console.log() to check it works
  var rng = Math.floor(Math.random() * 100);
  console.log(rng);
  // function determining action to take depending on range of number generated
  function choice() {
    if (rng <= 10) {
      console.log('Below or equal to 10');
    } else if (rng > 10 && 20 >= rng) {
      console.log('Above 10, up to 20');
