The aim of this puzzle: Use a For…of loop to draw a rainbow with a different color on each row.
Walkthrough of solution: A For…of loop is set up to loop through an array of colors. On each iteration (loop), the variable x will refer to the current element in the array. For example, on the 1st iteration, x has the value 'red', so the code in the code block:
drawBox(x);
newLine();
will draw 1 red box before jumping to a new line.
When this puzzle loads, the code block of the For…of loop is empty. To complete the puzzle, call drawBox(x), following by newLine(), so that a rainbow is drawn when the code runs.
Sample code solution:

for (var x of [
'red',
'orange',
'yellow',
'green',
'blue',
'indigo',
'violet'
]) {
drawBox(x);
newLine();
}
