I am confused. Continued working on my OS by following the third and fourth guide. Following the third guide everything went smoothly, I managed to make the windows moveable, closable, openable and so on. - But when continuing with the fourth guide I got so confused… I have no clue what I am supposed to do and what the guide wants me to do. Aaa Javascript you confuse me so much :( - I will probably take a break and try to resolve all of this another day….
