-# Prep exercise - traffic light
+you can finf the solutions in the follow links:
 
-Let's have a deeper look at the working of traffic lights this week so that we can practice logic and loops. In `traffic-light-1.js` and `traffic-light-2.js` you will find the same requirements but with different ways of representing the traffic light. Have a look through the files and solve them so you can see how the way we represent data affects the way we need to solve problems.
-
-## Things to think about
-
-- Which way of representing the traffic light did you find better? Why?
-- What happens if you change the loop to a `do-while` loop instead of a `while` loop? Why?
-- We could have also used a `for` loop to make the traffic light do 2 full rotations. Do you think that would be better? Why or why not?
