The aim of this puzzle: Build a band-name generator that outputs at least 9 different band name options.
Walkthrough of the solution: This puzzle features a “nested” for loop, which is a for loop inside another for loop.

For each iteration of the outer for loop, the inner for loop iterates completely. For example:

for (var a of [0, 1]) {
  for (var b of [0, 1, 2]) {
    print(a, b);

When the code runs, this will print:

In this puzzle, we will use a nested for loop to generate band names. To complete the puzzle, add 2-3 names to the outer for loop’s array, and 2-3 names to the inner for loop’s array.
Sample code solution:

for (var artist of ['Grace', 'Iggy', 'Summer', 'Josie']) {
  for (var band of ['Grasshoppers', 'Bugs', 'Cheese', 'Mechs']) {
    print(artist + ' and the ' + band);
