Can this diary teach us anything about slang used during wwii

Long Answer but you can paraphrase it: The most famous diary to come out of World War II was written by Anne Frank, a young Jewish girl who hid with her family from the Nazis in an Amsterdam attic. But Anne Frank was not the only person during that great global conflict to keep a daily record of her thoughts and actions. Many men and women, experiencing the thrills, horrors, uncertainties, novelties and boredom of a soldier or civilian’s life kept private diaries of their wartime experiences.
