 The above code takes the first value in the array and creates that many stars at random locations. Now, all we need to do is iterate through the entire array and do the same thing for each of the values. We will put the above code inside another loop that will run the same number of times as the length of the array (in this case, 5). You should also use a 'pause' block and a 'clear screen' block in between each constellation.

 Traversing an array means proceeding through the elements of the array in sequence. Note that there is a special loop in the Loops Toolbox drawer called ‘for element value of list’. This loop automatically takes each element of your array in turn and copies it into a variable called value.
